Talk Title:  Molecular Engineering of π-Functional Conjugated Materials for Photonics, Electronics, and Sensing

Abstract: Next generation active electronic materials used in devices are undergoing continual improvements to generate devices that are high performance, lighter, flexible, stretchable, and more energy efficient with lower cost. Carbon based novel solution processable π-functional conjugated materials are the focus of intense academic and industrial research since they are important class of soft materials for large area electronics including transistors, displays, sensors and light harvesting devices. The active organic semiconducting materials are emerging due to their tunable light absorption/emission, interesting charge transport properties, relatively adequate HOMO-LUMO energies and ink formulation capability.
In my talk, I will explain the various classes of conjugated carbon-based materials either as polymers, small molecules or quantum dots prepared via chemically and electrochemically using various novel aromatic conjugated building blocks. In this presentation, the design, synthesis, optoelectronic properties, and device performance of novel advanced materials for field effect/electrochemical transistors, perovskite solar cells, light emitting diodes, optical sensors and various sensing devices will be discussed. Such materials and devices have great potential in future electronics, energy, health, and environmental monitoring.

Talk Title: Modeling and Design of Superjunctions in Silicon Carbide

Abstract: Superjunctions yield a lower specific on-resistance, RONSP, for a given breakdown voltage, than conventional p-n junctions. We derive (a) a new theoretical lower limit of RONSP for an ideal balanced superjunction that is 30 % lower than prior works, (b) closed-form design equations for a practical superjunction considering process variations for the first time, and show that the optimum p-pillar aspect ratio is < 15 whereas prior works have tried raising this ratio beyond 25. We also propose charge sheet superjunction as a viable alternative to superjunction in SiC material to avoid complexities associated with fabrication of p-pillars in SiC.

Talk Title: Investigation and Comparison of Deep Acceptors in β-Ga2O3 using Defect Spectroscopies

Beta phase gallium oxide (β-Ga2O3) is a strong contender for next-generation high voltage and RF device applications. A key component of such devices is a semi-insulating, highly resistive buffer layer or substrate. To date, iron (Fe) has been the preferred acceptor impurity to achieve semi-insulating β-Ga2O3. Iron produces an energy level at EC-0.8 eV, which has been substantiated by theoretical and experimental studies and enables highly resistive material. However, it has also been shown that residual Fe impurities can result in device switching instabilities since the Fermi level can modulate the occupancy of the Fe trap state during standard biasing conditions. While progress to mitigate the impact of residual Fe impurities has occurred, there is also interest in exploring acceptors with much deeper energy levels to avoid device instabilities. Magnesium (Mg) and nitrogen (N) have emerged as candidates based on their predicted energy levels of EC-3.3 eV and EC-2.8 eV, respectively (H. Peelaers, et al., APL Mater. 7, 022519, 2019). This presentation will compare each acceptor, with a primary focus on N, using deep level optical spectroscopy (DLOS) and thermally based deep level transient spectroscopy (DLTS).
Here, N acceptors were introduced into HVPE-grown β-Ga2O3 by ion implantation. A uniform N-implantation profile was used targeting multiple doses in different samples, followed by an activation anneal. DLTS and DLOS measurements were applied before and after annealing. After implantation, multiple trap states appeared, most of which were removed by annealing, leaving a single, new state at EC-2.9 eV, with a Frank-Condon energy of 1.4 eV. The concentration of this state monotonically tracked with nitrogen concentration from SIMS. This energy level closely matches predicted values for an acceptor-like defect due to nitrogen atoms occupying the oxygen III sites, determined by density functional theory (DFT) calculations (H. Peelaers, et al., APL Mater. 7, 022519, 2019; Y.K. Frodason, et al. J. Appl. Phys. 127, 075701, 2020), The much deeper energy compared with Fe could imply a significantly lower operational instability than the shallower Fe acceptor at EC-0.8 eV. However, we found that the below midgap position of the NO(III) level, coupled with its small optical cross-section, complicates the trap concentration analysis by DLOS, which is important for understanding how to characterize very deep states in β-Ga2O3. Simultaneous hole emission to the valence band and electron emission to the conduction band was seen. Similar challenges might be present for Mg doping as well. The impact of this behavior on DLOS analysis is discussed, and a method to resolve this complication will be presented, which is needed to guide further optimization of this critical step in gallium oxide device development.

Talk Title: Error mitigation and the path to quantum advantage

Abstract: Quantum processors based on superconducting circuits have now reached a scale that is well beyond direct diagonalization. However, in the absence of fault tolerance, the central question is whether such noisy processors can provide useful computations. In this context, error mitigation techniques can provide access to noise-free observables even from today’s noisy processors. I will introduce these techniques, discuss the current state of quantum hardware and recent experimental results, and chart out an immediately accessible path to quantum computational advantage.

Talk Title: MEMS Physical Sensors with Integrated FET based Electromechanical Transduction

Abstract: MEMS sensors and devices have numerous applications spanning across consumer gadgets, automotive electronics, industrial medical, defence, aerospace etc. Despite the wide and increasing demands for MEMS-based devices such as sensors and actuators in diverse applications, unlike semiconductor technologies like CMOS/VLSI, the design and fabrication of MEMS/Microsystems is not fully standardized. Most of the commercially available MEMS sensors are based on passive transduction mechanisms such as capacitive or piezoresistive with inherent performance limitations. FET based active transduction schemes have the potential to overcome these limitations with ease in CMOS-MEMS integration as an additional merit. This talk would give a brief overview of our attempts towards indigenous development of MEMS physical sensors with FET based electromechanical transduction with scope for CMOS-MEMS integration.

Talk Title: A novel approach for recycling of waste silicon solar photovoltaic modules: A step to promote circular economy

Abstract: With the average lifespan of a solar module being 25-30 years, it is predicted that the cumulative waste generated globally would be around 78 million tonnes by 2050. Hence, developing a process for the recycling of this solar waste is crucial to prevent environmental pollution and to recover valuable materials. It is important that the end-of-life of solar modules should stay green to maintain the circular economy. Our work is focused on the recovery of valuable materials from spent crystalline silicon solar modules by a combination of physical, chemical, and thermal operations to de-laminate the modules and purify the materials. Through this process, an economically viable method was established to recover high pure silicon along with other components such as glass, copper etc.

Talk Title: Radio Frequency Micromachined Devices and Circuits for Microwave to millimeter Wave Applications

Abstract: When radio frequency microelectromechanical system (RF MEMS) based switches appeared more than 25 years ago, micromechanics have attracted huge attention for enabling near-ideal microwave devices. Since then, MEMS switches and circuits went through different development stages and are currently proving themselves commercially. Micromachining technology has the potential to become an enabling technology for microwave, millimeterwave to even sub-millimeterwave systems. Although, reliability of MEMS devices is one of the prime challenge to meet present state-of-the-art performances due to occurrence of multiple failure modes after few cycles of operations. This reliability becomes more critical when multiple MEMS switches operate simultaneously like in a multi-bit digital phase shifters. First phase primarily concentrates on the reliability improvements on MEMS based switching networks and digital phase shifters. It takes multiple iterations and extensive characterizations to conclude with a reliable MEMS phase shifters. Second phase briefly presents development of tunable bandpass filters utilizing MEMS switches for present 5G applications. Third phase briefly shows the potential of micromachined antennas for phased array networks. Finally, present webinar concludes with current research activities of RF MEMS in sub-millimeterwave regime.

Talk Title: Modeling, simulation and applications of engineered TFETs

Abstract:  The tunnel field effect transistor (TFET) has drawn considerable attentions for future generation low-power VLSI/ULSI applications due to its extremely low sub-threshold current and good switching characteristics. The TFET possesses low sub-threshold swing below the Boltzmann limit of 60 mV/decade of the bulk MOSFETs. However, the major drawback of the TFET is its very poor ON current. Several techniques have been introduced to improve the performance of the TFETs through various structural modifications. The present talk will introduce the performance analysis of some engineered TFET structures via theoretical modelling and commercially available TCAD simulations. Finally, some applications of the engineered TFETs in the SRAM design and level-free bio-sensors will also be discussed.

Talk Title: Advanced Power Devices Packaging

Abstract:  Si-MOSFET/IGBT finds wide application in personal computers, servers, micro-inverters, motor-drives, telecom systems, etc. Advent of WBG semiconductor technology has not been able to replace the Si Technology. However, due to the aggressive needs of the power management systems in terms of higher power-density, lower parasitic-inductance, lower thermal-resistance, Si semiconductor industry is still going through innovations to keep the performance of devices at optimum level.
Recent improvements in Si-device packaging technology have significantly optimized device parameters and figure-of-merits (RDS(ON)*Qg, Qrr, Esw). Furthermore, with the increase in system current requirements, optimization of these device parameters become important which resulted in advent of packages like DPAK, D2PAK, SO-8, CopperStrapTM SO-8, PowerPakTM, LFPAKTM, DirectFETTM, TOLL, sTOLL, etc. This talk will elaborate the evolution and trends in packaging technologies for achieving better device characteristics which can enable high performance product designs for automotive, energy, data center applications.

Talk Title: New market segments enabled by far-UVC technologies

Abstract:  Part of the ultraviolet spectrum from 200 nm to 230 nm wavelength, called far-UVC, is highly absorbed by proteins in the superficial inactive cells of the skin and eyes. This allows for direct exposure of far-UVC at effective doses for pathogen deactivation.
UV Medico develops and produces far-UVC solutions. Our products have the advantage of being suitable for continuous disinfection of both the air and surfaces in occupied spaces. As such, far-UVC has a broader application area than conventional germicidal UV light sources which damage living cells. The latter are restricted to applications without direct human exposure, such as upper room ventilation systems and disinfection robots.
Research on far-UVC has recently triggered a movement to increase exposure limits and adapt regulations accordingly. With the progressive adherence of regulatory agencies, new applications are enabled. This presentation will focus on the food industry as an example of the diverse application field.

Talk Title: Enabling Technologies for Low-Cost mmWave SATCOM Terminals

Abstract:  mmWave 5G has received a lot of attention due to its ability to deliver extremely high data rates to the user, while also posing challenges to the designer related to the need for large-scale arrays, high-power and high-efficiency power amplifiers, and advanced mmWave packaging. However, over the past year or two, there has been a significant rise in the interest in mmWave SATCOM, driven by the lowering of the barrier to launch satellites into orbit. SATCOM ground terminals, however, pose challenges that are akin to those posed by 5G on steroids – the arrays are 10x larger in size, amplifier efficiency is even more important, <2dB LNA noise figure is required, and electromagnetic, mechanical and thermal packaging challenges are even more severe. This presentation will touch upon various enabling technologies for mmWave SATCOM ground terminals – RF-SOI technologies, high-power high-efficiency mmWave PA design, extremely-low-NF LNA design, and scalable multi-beamforming.

Talk Title: Two-Dimensional Material-based Higher-Order Neuromorphic Computing with Dynamic Weights

Abstract:  The increasing complexity of deep learning systems has pushed conventional computing technologies to their limits. While memristor is one of the prevailing technologies for deep learning acceleration, it is only suited for classical learning layers where two operands, namely weights and inputs, are processed at a time. Meanwhile, to improve the computational efficiency of deep learning for emerging applications, a variety of non-traditional layers, requiring concurrent processing of many operands, are becoming popular. For example, hypernetworks improve their predictive robustness by simultaneously processing weights and inputs against the application context. Two-electrode memristor grids cannot natively support such operations of emerging layers. Addressing the unmet need, this talk discusses two-dimensional material-based neuron and synapses that can be controlled by multiple gate terminals. Thus, exploiting crossbar’s gate controllability, multiple operands could be concurrently processed within the same crossbar. Many advanced inference architectures that can generalize beyond a typical passive crossbar thus become possible. Overall, the ultra-low-power, higher-order processing capacity of the discussed gate-tunable crossbars and neurons harnesses high robustness and efficiency of emerging deep learning layers within area/power-constrained devices such as mobile, sensor, and embedded systems.

Talk Title: DTCO: How the industry has evolved

Abstract:  Since 1965, when Gordon Moore made his now famous self-fulfilling prophecy, optical scaling and material systems enabled a direct 0.5x area scaling node over node, for the next 30 years or so. While in no way was this scaling straightforward i.e.: engineering Innovation was needed; We were not approaching physical limits of material systems or optical limits of the printing systems. As area scaled, device and parasitic capacitance scaled almost linearly, without appreciable increase in effective Resistance or Leakage currents. This fulfilled the conditions for Dennard’s Law, enabling a geometric shrink driven performance boost and power reduction. In the early 2000s, for the 32/28mm node the rules of engagement changed, driven primarily by increase in leakage. However, design was still somewhat isolated from the disruption by clever technology decisions. By the time the industry was developing the 22/16nm nodes in 2005, it was no longer possible to optimize technology alone due to limits of optical/patterning systems, and the term DTCO was coined. Since then, DTCO has evolved to design around patterning and integration challenges, determine device and interconnect choices to drive PPA as we push the physical electrical limits of semiconductor manufacturing. My talk will cover some interesting aspects of how DTCO has impacted Technology Definition since its conception in 2005 to current day.

Talk Title: Tunable Many-body Interactions and Induced Superconductivity in a Helical Luttinger Liquid

Abstract:  The interplay of topology, superconductivity, and many-body correlations in 1D has become a subject of intense research for the pursuit of non-trivial superconducting pairing. The boundaries of atomically-thin topological insulators in 2D – amongst them the quantum spin Hall (QSH) insulator – provide a natural realisation of strictly 1D electronic structure with linear (Dirac) dispersion and spin-momentum locking (helicity).
We show that the topological edge states of the QSH insulator 1T’-WTe2 harbour a strongly correlated 1D electronic ground state – a helical Tomonaga-Luttinger Liquid (TLL) – whose many-body Coulomb interactions can be effectively controlled by the edge state’s dielectric environment. This demonstrates tunability of a helical TLL in both its fundamental dependencies on potential and kinetic energy terms, respectively. Finally, we show that super-conductivity can be induced into the 1T’-WTe2 quantum spin Hall state by proximity-coupling to a superconducting van-der-Waals substrate, giving rise to an induced superconducting order parameter as large as 0.6meV in WTe2, stable beyond a B=2T magnetic field.

Talk Title: Fundamentals of thermoelectric engines with twisted 2D bilayers of graphene

Abstract:  Thermoelectricity is an unconventional but extremely sensitive probe to the effects of electronic interactions in solids. Thermoelectric measurement often complements standard electrical transport and detects electronic correlations through departure from the well-established Mott semiclassical framework. Recent emergence of twisted bilayers of graphene provides a new versatile platform to explore not only several fundamental aspects of thermoelectricity at the atomic scale, but also design a new class of thermoelectric devices. I shall present how thermoelectricity can probe the inter-layer coupling in twisted bilayers, and exploit the understanding in realizing a unique class of heat engines.

Terahertz (THz) technologies have been identified as a critical candidate for the emerging 6G communication with the potential to provide ubiquitous connectivity and remove the barrier between the physical, digital, and biological worlds. Nonetheless, the existing THz photonic on-chip communication devices suffer from backscattering, bending loss, limited data speed, and lack of active tunability. Here, I will describe a new class of on-chip THz photonic topological devices consisting of low-loss, broadband single channel 160 Gbit/s communication link and critically coupled high-Q (Q ~ 106) cavities built on Silicon Valley-Hall Photonic Crystal. Silicon topological photonics will pave the path for augmentation of CMOS-compatible hybrid electronic-photonic driven terahertz technologies, vital for accelerating the development of 6G communications that would empower societies with real-time terabits per second wireless connectivity for network sensing, holographic communication, cognitive internet of everything, and massive digital cloning of the physical and the biological world.

Talk Title: Characterisation and Modelling of the Switching transitions of WBG Devices

Abstract:  Silicon Carbide MOSFETs (SiC MOSFETs) fall into the class of wide band gap (WBG) power devices. These devices are commercially available in the voltage range of 600-3300V and compete with the state-of-the-art Si-insulated gate bipolar junction transistors (IGBTs). Superior material properties of SiC MOSFET lead to smaller die sizes. This results in faster switching transients and lower switching loss. However, it excites device and circuit parasitic that may lead to prolonged oscillation, high device stress, spurious turn-on and EMI-related issues. So, the benefit of using SiC MOSFET as a power device comes with numerous design challenges resulting in slow commercial adaptation. It is predicted that the overall market share of WBG devices (SiC and GaN together) will be roughly 10% of the total market for power semiconductors by 2025. To overcome the design challenges and fully utilise the benefits of fast-switching SiC MOSFETs, a better understanding of switching dynamics is essential. However, the switching dynamics of SiC MOSFET are different compared to its Si counterpart due to the highly non-linear device characteristics and participation of circuit parasitic in the process. In this talk, we will discuss our recent work on developing an analytical model of the switching dynamics for hard and soft transitions of SiC MOSFET by simplifying the complex non-linear dynamics predicted by the behavioural model. The developed model, given the device-related parameters extracted from the data sheet, estimated or measured circuit parasitic, can predict lost switching energy, rate of change of device voltage etc., necessary for a successful power converter design through computation with sufficient accuracy.

Talk Title: Ultra-low-power steep-slope transistors based on laterally confined monolayer MoSi2N4

Abstract:  Leakage current in transistors has become a critical limiting factor for realizing ultra-low-power transistors. The dominant part of the leakage current arises from the long tail of the thermally excited carriers of high energy. We solve this problem by using narrow bandwidth semiconductors which limits the thermionic leakage current by filtering out the high energy carriers. We demon- strate this by using laterally confined and passivated monolayer MoSi2N4 as a channel material in two-dimensional transistors. With this solution, the subthreshold slope can be reduced to remark- ably low values of up to ∼ 20 mV/decade, compared to the thermally limited value of 60 mv/decade in conventional transistors at room temperature. We show that the unique electronic properties of narrow bandwidth conduction and valance bands is also shared by several other materials in the same series. This opens up new avenues for effectively tackling the OFF state current leakage and power dissipation problem and realizing ultra-low-power transistors.

Talk Title: Linear and nonlinear effects in 2D Suspended Structures

Abstract:  Vibrating membranes fabricated using 2D materials are extremely sensitive to various stimuli. In this talk, I’ll present our efforts towards using these thin structures as sensors. One of these is a strain sensor fabricating using graphene on a thin silicon diaphragm. These tiny structures vibrate at very high frequencies (10-100MHz) and are exquisitely sensitive to changes in the strain. However, nonlinearities in these devices also constraint their use as linear sensor. In the talk, I’ll demonstrate methods for controlling and manipulating these nonlinearities. I’ll show how our inability to produce perfect devices leads to nonlinear effects and our ability to control and cancel out nonlinearities leads to enhancement of signal to noise ratio. This regime of near cancellation of the two strongest nonlinearities is not only useful for applications but also to observe higher order nonlinearities and nonlinear damping.

Talk Title: Waferscale Computing

Abstract: Fueled by the tremendous growth of new applications in the domain of big-data computing, deep learning, and scientific computing, the demand for increasing system performance is far outpacing the capability of conventional methods for performance scaling. Traditionally, performance and energy scaling has relied on transistor and silicon scaling. However, developing chips, often very large ones in the advanced technology nodes, is becoming very challenging and costly. Moreover, system performance is often limited by inter-die connections. Today, dies with different functionality are packaged and integrated using PCBs. Unlike silicon features, package and PCB features have barely scaled (about 4-5x) over the past few decades. This severely limits performance and efficiency of processor systems. Traditional scale-out system building, and integration methodologies are failing to deliver the performance today’s applications (such as artificial intelligence, big-data processing etc.) demand. As a consequence, future performance, power, and cost improvements cannot come from transistor technology alone. Then, how do we enable “System scaling”?

To target scale-out systems, we propose chiplet-based waferscale processors to dramatically reduce inter-die communication overheads. To that end, we developed the Si-IF technology where bare dies can be tightly integrated on a waferscale interconnect substrate to build scale-out processors up to a size of an entire wafer. However, building such a large consolidated waferscale system has its own challenges. For the first time, we explored the design space of waferscale power-delivery networks, cooling and trade-offs of yield and inter-GPM network topologies, etc. I will discuss some of these challenges and solutions that we developed to architect a large shared memory waferscale prototype system. Next, I will make a case for waferscale GPU and waferscale graph acceleration, where we leverage the massive bisection bandwidth and sub-1ns inter-die latencies to build high-performance computing systems. Our work shows that massive gains in excess of 5-10x can be achieved in terms of both performance gains as well as system energy using waferscale integration.

Talk Title: Utilizing Quantum Geometry and Topology for Enabling Integrated Chiral Photonics

Abstract: Classical and quantum computing devices need to ferry vast amounts of data and optical interconnects provide a promising approach allowing faster speeds and larger bandwidths. Critical interconnect components are light sources, waveguides and detectors. Currently, the information is encoded in intensity and frequency but other degrees of freedom (DOFs) such as photon-spin and spatial orbital angular momentum modes (OAM) should be utilized to enhance the capacity of optical links. Therefore, new materials and devices that can produce, transmit and detect light with complex polarization and spatial modes are needed. We will discuss recent developments towards the development of on-chip lasers, waveguides and photodetectors that are sensitive to photon spin and OAM modes that can enable the development of integrated chiral photonic systems.

Talk Title: Lithium Voids Precede Dendrite Growth in Solid State Lithium Metal Batteries

Abstract: Solid-state lithium metal batteries (SSLMBs) that utilize metallic lithium as an anode offer high energy density and potentially long cycle and calendar life. However, stable plating and stripping of lithium in cells employing inorganic solid electrolytes, especially at current densities >0.2 mA/cm2, has been a challenge. In this talk, we will discuss the origins of dendrite growth in SSLMBs employing inorganic solid-state electrolytes. We show that there is a strong correlation between the onset of dendrite growth and the observation of lithium voids at the interface with the solid electrolyte. We discuss the properties of interlayers and propose descriptors for identifying interlayers that could further increase the current densities for cycling lithium without the undue necessity for high stack pressure.

Talk Title: Indigenous GaN MMIC Technology

Abstract: Future trends for next generation strategic systems require multifunctionality and modularity like combining radar, communications, and electronic warfare in one system. This higher level of functional integration improves system performance through heightened awareness, improved responsiveness, and mission execution. The use of gallium nitride (GaN) MMIC as key component enables higher performance of systems meeting the requirements in small size with high power and hence GaN MMIC are emerging as an alternative or replacement for laterally diffused MOSFET (LDMOS) components. In most of next generation systems GaN MMIC technology is being considered because of high power density, high efficiency, wide bandwidth, and exceptionally long life. GaN on SiC has superior properties like higher breakdown voltage; higher saturated electron drift velocity and higher thermal conductivity. Hence GaN HEMTs also offer greater power density and wider bandwidths compared to Si; GaAs; and GaN on Si transistors. As shorter gate length GaAs and GaN transistors become available, coupled with improved circuit design techniques, new devices are becoming available that can perform comfortably to millimeter wave frequencies, opening new applications that were hard to contemplate a decade ago. This paper will briefly describe the indigenous GaN semiconductor technology that is enabling these developments to achieve optimum performance of devices, circuits and subsystems based on this technology.

Talk Title: Polariton lasers in organic molecular materials

Abstract: Exciton-polaritons, half-light half-matter quasiparticles that form in optical cavities have become a highly attractive candidate to realize Bose Einstein like condensates in the solid state that emit coherent radiation. Also called polariton lasers, these systems show lower threshold than the more conventional photon lasers because they do not need population inversion. Organic molecules have emerged as an appealing system to realize polariton lasers owing to their ability to operate at room temperature. Following a brief introduction to polariton lasers, I will present our recent work on realizing a universal platform for achieving polariton lasing using commercially available dyes using a small molecule ionic isolation lattice (SMILES) host. Possibility to realize lattices of polariton lasers and their potential as analog Hamiltonian simulators will also be discussed.

Abstract: We present two complementary viewpoints for combining quantum computers and the foundations of quantum mechanics. On the one hand, ideal devices can be used as test beds for experimental tests of the foundations of quantum mechanics: We provide algorithms for the Peres test for complex numbers in quantum superpositions and the Sorkin test of Born’s rule. On the other hand, noisy intermediate-scale quantum devices can be benchmarked using these same tests. These are deep quantum benchmarks based on the foundations of quantum theory itself. We present test data from Rigetti hardware and the IBM qiskit simulation platform.

Abstract: Sustainability and health are two of the global challenges recognized by UN. Electronics is the pillar that supports the innovation in these sectors. However, current electronic components are non-biodegradable and release toxins in environment, while the implanted electronics is not compatible with soft human tissues.

Talk Title: On-chip System level IEC ESD protection issues in Automotive ICs

Abstract:  In this talk, unique failure mechanisms in high voltage Silicon Controlled Rectifiers (SCR) under IEC stress are discussed. In one case, the presence of a common mode choke in the stress path was found to change the current waveform shape that the electrostatic discharge (ESD) protection device experiences on-chip. Minor variations in the stress current waveform shape for specific IEC stress levels are found to cause an unexpected window failure in DeNMOS based SCR. In second, Air-Discharge IEC failure in Bi-Directional SCRs that are sensitive to IEC measurement conditions via the pulse rise time are investigated. 3D-TCAD simulations are used to develop the physical Insights of the failure and propose the device level engineering solutions to mitigate the IEC failures.

Talk Title: Manganite based RRAM for Stochasticity Control for Boltzmann Machine

Abstract: Non-filamentary manganite-based RRAM provides richness in behavior & controls due to the interplay of ionic, thermal, and electron conduction. We have shown that set & reset processes are enabled by positive vs. negative feedback leading to polarity-controlled stochastic vs. deterministic switching. The stochastic set enables a probabilistic switching in a neuron for a Boltzmann Machine. The deterministic reset enables excellent HRS control which enables weight update. Further, it enables highly controlled initialization of the HRS state that produces a very controlled stochastic switching distribution that remains drift free over time. Such stationary distributions enabled by deterministic/stochastic device physics produces improved performance in NP-Hard graphical optimization problems like maximum cut (Max-cut).

Talk Title: Revisiting doping mechanisms in a mixed electronic-ionic conductor PEDOT:PSS

Abstract: The mechanism of doping and de-doping in conjugated polymers such as PEDOT:PSS has been widely discussed on account of their application in bioelectronics from electrochemical batteries/supercapacitors to neural electrodes and transducers. In a conventional theory, there are three expected mechanisms of doping (i) Capacitive, leading to box shaped CV characteristics, whereby electrical double layers are formed at the surface of the polymer and the counter-electrode. This type of a film shows a capacitance independent of thickness. (ii) Faradaic, in which under positive bias, holes move towards the counter-electrode and react with species in the electrolyte leading to redox peaks in the cyclic voltammetry and (iii) Volumetric electrochemical doping, which is a combination of the above two, caused largely by cation injection into the bulk of the film, leading to electronic-ionic coupling of the holes and cations [1-3].
We demonstrate that the doping mechanism of K+ in PEDOT:PSS is more complex than these simple scenarios. Our films are able to retain more ions in a Faradaic reaction than via purely capacitive doping, pointing to coupling between the sulfonate anion and cation.

Talk Title: 2D Dielectric Materials for Emerging Nanoelectronic Devices

Abstract: Two dimensional (2D) dielectric materials are amongst the key drivers enabling the realization of next generation nanoelectronic devices in the future [1]. Hexagonal boron nitride (h-BN), 2D mica and Fluorinated graphene have recently attracted a lot of attention as 2D dielectric materials [2,3]. In particular, h-BN emerges as one of the promising dielectric materials for graphene and other 2D layered semiconductor based nanoelectronic devices. The h-BN exhibits perfect match for graphene as they share many similarities. Mica dielectric material used as a substrate for various heterogeneous 2D material structures due to its excellent thermal stability, surface flatness, light transmittance and chemical resistance. Fluorinated graphene is another 2D dielectric material which demonstrates excellent dielectric properties with fast and scalable processing. Importantly, there is limited insight and conclusive evidence on the physics of degradation, reliability and breakdown (BD) in these 2D dielectric materials. Here, we highlight important findings on the mechanism of degradation and BD in h-BN and Mica dielectrics from the device level to localized nanometer scale regions of 2D dielectrics. Nanoscale analysis tools (Conductive atomic force microscopy (CAFM) and transmission electron microscopy (TEM)) are used to assess the nanoscale performance of the 2D dielectrics; local degradation due to dielectric wear-out and subsequent breakdown.

Talk Title: Strain-driven quantum devices

Abstract: Topological order and materials have been at the center of attention in condensed matter physics and engineering. Topological materials, a new quantum state of matter, are a family of quantum materials with boundary states whose physical properties are robust against disorder. Therefore, there have been few examples for a topological phase transition realized experimentally, even fewer cases for an in-situ tuning of the topological phase. For the first part of my talk, I will discuss our results
and methods to apply uniaxial strain in topological van der Waals quantum materials and how it influences its electrical properties. Our results point towards a topological phase transition of the system tuned by in-situ uniaxial strain. For the second part of my talk, I will discuss our approach to creating dynamic strain in van der Waals quantum materials and how to control the electron and excitons dynamics in such systems. Our results could pave the way for engineering novel quantum devices as well as a step towards a solid-state quantum simulator platform.

Talk Title: Spatially Controlled Growth of 2D Materials

Abstract: The surface potential of graphene can be modulated with strain and doping by engineering the underlaying sub-surface in which the graphene resides on. Here we discuss a detailed investigation to correlate the influence of the underlying sub-surface on modulating the surface potential of graphene on a diamond like carbon (DLC) substrate through a heterointerface containing trapped gallium in uniquely designed spatial structures. Through our heterointerface engineering approach of the graphene surface potential landscape, we show selective area growth of 2D materials on the graphene surface . This study will provide a deep understanding on the influence of graphene surface potential on the nucleation and surface diffusion process for the growth of chalcogenide 2D semiconductors.

Talk Title: Towards reliable circuits using NC/FEFETs

Abstract: In this talk, we mainly describe our work in understanding the physics of multiple domains, dielectric (DE) phase in FE layer, interface traps in NC/FeFET devices and their impact on circuit reliability. We also discuss the impact of polarization asymmetry in the FE layer due to drain-source voltage in NC/FeFETs. We discuss that the presence of DE phase causes non-uniformity in the polarization and potential contour inside the FE-layer in the gate-dielectric stack. The randomly varying fraction of DE phase, therefore, introduces a higher reliability concern for NC-FETs. In FeFETs, we observe and explain that there exists a certain DE percentage threshold below which the increase of the DE phase does not significantly impact the device memory window. We observe that another reliability issue in NCFETs is caused by the traps at the interfaces of silicon, silicon-di-oxide and hafnium oxide or bulk hafnium oxide traps, which change the FE polarization.

Talk Title: MICRO-NANO INTEGRATED SYSTEMS FOR LIFE SCIENCE APPLICATIONS

Abstract:  In this presentation, we will talk about the in-situ synthesis of Au-PDMS and Ag-PDMS nanocomposites both at the macroscale and inside the channel of a microfluidic chip. The nanocomposite has been successfully used for sensing of antibody-antigen interactions, allowing the detection of various important proteins.

The effect of the particle`s shape on the properties of nanocomposites and their sensing abilities has also been studied by synthesizing nanostar particles and integrating them into microchannels. Because of the biocompatibility and non-toxicity of gold and silver nanoparticles, their nanocomposites can be used for plasmonic detection of biological entities in cancer research.

Talk Title: CMOS scaling: From Design into System Technology Co-Optimization

Abstract:  Scaling is driven by the perspective of more function per unit cost. This paradigm has essentially been fueled with increasing transistor density by building ever more compact devices and finer interconnect capabilities. We are approaching records in feature sizes that starts questioning its viability moving forward. The entire Mendeleev table has been screened and manufacturing machines reach extreme levels in precision. However, an SoC is not composed of a monolithic set of functions, from compute blocks to memorization very different functions are expected from CMOS devices, not to mention the whole infrastructure that wraps the system (power and clock distribution, short signal nets and long signal nets, IOs and PLLs,…). The SoC is a vastly heterogeneous system. In order to keep scaling system performance, technology will not need to embrace that heterogeneity and find ways to leverage unique technology capabilities that improve system performance. This can only go hand in hand with a revision of system design practices and introducing novel architectures. CMOS Scaling is entering the era of System-Technology Co-Optimization. We will be talking about concepts leaning in that direction, such as backside processing and bonding technologies for smart partitioning, and extrapolate to the broader vision of the CMOS heterogeneous platform: CMOS 2.0.

Abstract:  The photovoltaic industry has reached a major milestone of installed global capacity of 1TW. The desert regions are ideal locations for installing large power plants. However, the expectations of PV system operating for 20-30 years or more can be challenging due to the harsher climatic conditions. Therefore, improving the risk associated with weather-induced degradation of PV modules will reduce uncertainity in lifetime energy production, which in turn reduces financial risk and improves financing opportunities for projects located in these regions.

Talk Title: Building and Memory Centric World

Abstract:  We live in an era which is more memory-centric than ever. Factors that contribute to the ever increasing importance of memory are – (i) Saturation of Moore’s law, (ii) ease of generating enormous amounts of data and (iii) exciting new material properties. The nature of present day data intensive applications is such that, excellence in computational performance cannot be achieved alone on the basis of raw transistor scaling or linearly increasing the number of processing cores. A fundamental shift in the vastly successful Von Neumann computational paradigm is needed to overcome the bottlenecks associated with data-intensive real time applications. This is where next generation Non-Volatile Memory (NVM) begins to play a very significant role. Our research group at IIT-D, has been actively working on exploiting the characteristics of emerging NVM nanodevices and nanomaterials for a multitude of novel applications. We have considered emerging technologies such as OxRAM, CBRAM, PCM, RRAM, STT-MRAM etc. building an entire memory-centric application ecosystem comprising of various hybrid CMOS-NVM circuits. Applications realized include: Supervized and Unsupervised Learning (SNNs, CNNs, BNNs), AI Edge-Inference & Training, Sensing, Security, and in-Memory Computing.

Talk Title: Strain Insensitive Thin Film Transistor Circuits

Abstract:  Thin film transistors (TFT) promise high density integrated circuits and systems on diverse substrates such as glass, plastics and textiles. Recent years have seen a growing interest in the development of integrated systems that can both bend and stretch. These circuits are developed on elastomeric substrates that have a relatively low modulus of elasticity.
However, such requirements pose interesting questions related to the design of TFT circuits on these substrates. If there is positive strain along the source-drain direction, it is known that the threshold voltage reduces, and mobility increases in metal oxide TFTs. Based on this understanding, the question one can ask is – can we design TFT circuits whose transfer function remains strain independent? Here I discuss some key ideas that may enable the design of such circuits.

Talk Title: Sustainable Materials and Design Approaches for Soft Electronics and Robotics

Abstract:  Modern societies rely on a multitude of electronic and robotic systems, with emerging stretchable and soft devices enabling ever closer human machine interactions. These advances however take their toll on our ecosystem, with high energy demand, greenhouse gas emission and environmental pollution.
Mitigating some of these adverse effects, this talk introduces materials and methods for soft systems that biodegrade. Based on highly stretchable biogels and degradable elastomers, our forms of soft electronics and robots are designed for prolonged operation in ambient conditions without fatigue, but fully degrade after use through biological triggers. Electronic skins provide sensory feedback. 3D printing of biodegradable hydrogels enables omnidirectional soft robots with multifaceted optical sensing abilities. Enabling autonomous operation, stretchable and biodegradable batteries are introduced that power wearable sweat sensors.

Talk Title: Dual Active Bridge: Closed Form Equations for Voltage Fed and Current Fed Converters with Soft Switching Criteria.

Abstract:  Dual Active Bridge is becoming popular day by day because of the high power handling
capability, ease in achieving soft-switching, simpler operation, etc. 
It is a core interfacing component in High Frequency Links power conversion systems
for bidirectional power such as in solid state transformer (SST) etc. Isolation through
high frequency transformer sometimes also aid in achieving a more efficient solution by
proper choice of turns ratio. Here analysis has been carried out for an application which has a moderately high turns ratio. The focus was to arrive at a design methodology which yield minimum loss. For this probable topology candidates was studied and a comparative analysis was made. This design methodology can also be extended and tailor made for any specification. This talk revolves around the design of a DAB Converter for minimum loss.
Two types of DAB- Voltage-Fed and Current-Fed, have been studied extensively and then
the design of the topology is shown with comparison.

Talk Title: Compact Modelling and Unconventional Applications of 3D NAND Flash Memory

Abstract:  With applications ranging from portable flash drives to SSDs and cloud storage, 3D NAND flash memory has become ubiquitous in this era of internet of things (IoT). However, lack of a proper framework for analyzing the efficacy of 3D NAND flash memory has remained the bottleneck for circuit designers and system architects in this direction. In this talk, we present the first behavioral compact model for 3D NAND flash memory which effectively captures the parasitic coupling components while accurately reproducing the static characteristics. The developed compact model also enables the characterization of stochastic analog behavior. The possibility of exploiting the inherent variability of the 3D NAND flash memory for realizing an adversary-attack resilient strong physical unclonable function (PUF) circuit would also be discussed.

Talk Title: The role of heterogeneous integration in emerging device development

Abstract:  While heterogeneous integration has always been practiced in electronics packaging, the scale in conventional packaging has been macroscopic with packaged dies or chips integrated on a printed circuit board at ball grid array pitches of several hundred micrometers and trace pitches of tens of micrometers and inter die distances in the range of a few to several mm. In the last several years, the advent of more silicon-like substrates and the adoption of silicon technology, these dimensions have scaled considerably. At UCLA chips for example we have pioneered sub-10m bump pitches, inter-die spacings of tens of m, and wafer scale integration. Other approaches such as pseudo-monolithic integration where disparate devices and materials are assembled on say on processed silicon and interconnected lithographically at a ~100 nm scale pitches promise to upend the potential of classical approaches of trying to integrate everything on a CMOS wafer. In this talk, we will review these developments, their potential and also address some of the limitations. These new developments are indeed commercially viable and will lead to increased functionality at lower cost and size, enabling a “Moore’s Law” at the system level.

Talk Title: Engineered Carbon Materials for Sodium Ion Hybrid Capacitors

Abstract:  Carbon materials, including carbon dots, carbon nanotubes, graphene, graphite, hard carbon, etc., have received greater attention due to their diversity, abundance, and favourable properties. The properties of carbon materials are easily tunable by doping with other elements or making composites with other materials.1 The unique chemical and structural features allow the possibility of engineering these materials, thus offering them unlimited advanced applications in energy storage and conversion.2 Here, efficient strategies to synthesise porous and hard carbon materials with significantly improved surface area and porosity features are explored for their applications in hybrid ion capacitors (HICs).3 For instance, engineered carbon samples with ‘open’ and ‘closed’ pores are synthesised to explore the sodium charge storage mechanism in hard carbon anodes. In-depth studies using different physicochemical techniques revealed strong evidence for adsorption/insertion-pore filling mechanism.4 The talk will also highlight our recent efforts on mass balancing of hybrid ion capacitor electrodes that could be employed as a design tool to guide the selection of optimized HIC devices for the intended applications.5

Talk Title: Phase change photonics and interfacing it with electronics for emerging AI hardware

Abstract:  The current buzz in the semiconductor industry is heterogeneous integration. As the industry moves forward with several applications being data driven, there is a clear trend towards the convergence of computing, communications, sensing and control technologies. Packaging will play a significant role in enabling the convergence of these technologies.
On the communication side emerging 5G mmWave frequencies are projected to support enormous bandwidth with 1-10Gps data speeds. Active research is ongoing to increase the data speeds even more by moving to higher frequencies in the sub-THz frequency range namely, 6G with projected data rates of 1Tbps. Such applications can only be possible with advanced packaging solutions.
This presentation addresses the needs for beyond 5G (such as 6G) communications and the importance of packaging to fulfill these needs. The progress made on glass interposer-based solutions at Georgia Tech’s Packaging Research Center will be discussed along with future needs as we progress towards sub-THz frequencies.As the race towards new hardware that goes beyond the non-von Neumann processor for applications in machine learning and artificial intelligence heats up, photonics is emerging as a promising contender. It is clear that a future solution will have to embed elements that involve both photonics and electronics, ideally within the same chip. In this talk, I will cover fundamental research on device concepts using functional materials that underpin many of the developments over the last decade and present some of our recent work in this area.

Talk Title: Charge Based Compact Model (ICM) for GaN based HEMTs

Abstract:  A computationally efficient compact model of GaN-based HEMTs suitable for DC, small signal as well as transient simulations is presented.
At first, a unified expression for 2DEG charge density is formulated. Considering drift-diffusion model and charge linearization in the channel, an expression for the drain current is derived in terms of the electron charge densities at the source and drain ends. Other effects such as DIBL, CLM, vertical field dependence on mobility and self-heating are incorporated. The access regions are modelled using additional HEMTs similar to the intrinsic transistor. A model for gate-to-source and gate-to-drain currents is derived in terms of the terminal charges, which are obtained using Ward-Dutton charge partitioning scheme. The model includes the effect of buffer traps and is able to capture the dynamic behaviour of HEMTs and current collapse.
The model equations are implemented in Verilog-A and validated by comparison with experimental data for a wide range devices and under different operating conditions.

Talk Title: Electrostatics of bulk versus nanoscale junctions

Abstract:  Nanoscale devices based on atomically thin semiconductor layers, nanowires or nanotubes consist of PN junctions as either essential or parasitic elements. The mathematical treatment of the electrostatics of these junctions has been different for different geometries. We present a unified modelling approach based on a common set of approximations related to the electric field/potential distributions, and obtain simple analytical formulas for the depletion width, and the field and potential distributions. We show that the depletion width dependence on potential drop and inverse of doping varies from being square root in bulk to linear in atomically thin layers and exponential in nanowires/nanotubes. Further, we propose an effective medium theory, showing that an array of nanoscale junctions behaves as a bulk junction with effective permittivity and doping.

Talk Title: Power Electronics Energy System (PEES)

Abstract:  Driven by innovations in power semiconductor technology, decreased cost in solar, wind and energy storage technology, and the strong need to decarbonize every sector of our society, power electronics-based generations are positioned to replace today’s synchronous generator as the governing generation technology in the future. Simultaneously, electrifications on the load side are also power electronics based, hence creating a power electronics energy system (PEES) that encompasses generation, transmission, distribution and load. Due to the flexible and fast controllability of power converters, PEES can potentially outperform today’s energy system and achieve higher energy efficiency. A complete DC based PEES is also feasible. However, there are many challenges in designing and operating a PEES. This talk will provide an overview of power electronics technology, focusing on the state of the art from hardware and control point of view. New opportunities enabled by emerging power electronics technology in grid applications will be highlighted. The talk will also discuss gaps and research needs for a power-electronics based grid.

Talk Title: Up-conversion of terahertz phonons via nonlinear coupling

Abstract:  In this work, we demonstrate dynamic control of the lattice by using THz radiation. We use THz pulses with intense electric fields (~ kV/cm) to induce lattice non-linearities, which allow us to couple the low energy phonon modes to higher energy, silent optical phonon modes at ≈ 1.17 THz in the spin-ladder system, Sr14Cu24O41. Due to the coupling, we observe an enhancement in the transmission spectrum, i.e., transmittance > 1, near 1.17 THz. Hence, we demonstrate that it is possible to control inaccessible phonon modes with THz radiation indirectly. This provides opportunities to alter such material systems’ electronic and magnetic properties dynamically using THz radiation.

Talk Title: Interfacial Stabilization of Electrode Materials for Energy Storage

Abstract:  Understanding fundamental degradation mechanisms of electrode materials (EMs) , and their mitigation strategies, are challenged by constraints of the liquid electrolyte environment and the complexity of electrode/electrolyte interphase formation, namely the solid electrolyte interphase (SEI) layer which forms, grows, and changes (on the electrode interface) with battery usage.

Talk Title: Programmable Silicon Photonic Circuits

Abstract:  

Programmable photonic circuits are chips that manipulate light, and where the flow of light can be configured through a layer of electronics and software. This contrasts strongly with most photonic chips today, which have a fixed flow of light, custom-designed for one application. Programmability on a photonic chip means that the connectivity and functionality can be reconfigured, or even completely synthesized at run time. This is reminiscent of field-programmable gate arrays (FPGA) or digital signal processors (DSP) used in digital electronics. We discuss the basic photonic technology blocks for programmable photonic circuits, and the technological layers around these chips to make them programmable. The programmability in itself significantly lowers the threshold to experiment with photonic circuits, and could accelerate adoption and application developments.

Talk Title: High Energy and High Power Supercapacitors Using Nanocomposites for Consumer Electronics

Abstract:  There is an indispensable demand for development of alternative energy sources which would partially or completely replace the utilization of conventional fossil fuels as the combustion of fossil fuels leads to adverse effects on the environmental eco-system. Among electrochemical energy systems, supercapacitors have huge potentials for meeting the power requirements of consumer electronics which require high power. In particular, power density of the conventional lithium-ion battery (LIB) is not suitable, hence, high power device is demanded for hybrid electric vehicles (HEVs) and electric vehicles (EVs). However, low voltage and poor energy density of the supercapacitors are to be upgraded. In this talk, recent progress made on the electrode materials, in particular, oxide-based nanocomposites for high energy and high power supercapacitors/supercapattery would be presented.

Abstract:  Using state-of-the-art quantum transport based device modeling, we propose novel “topo-tronic”device constructs – providing an effective route to channelize the tantalising possibilities offered by topological quantum materials for emerging device design [1]. We propose a topological quantum field-effect transistor (TQFET) that be engineered to enable sub-thermionic transistor operation coupled with dissipationless ON-state conduction. Detailing the complex band translation physics related to the quantum spin Hall effect phase transition, It is the demonstrated transitions between the quantum spin-valley Hall (QSVH) and the spin quantum anomalous Hall (SQAH) phase can ultimately ensure the topological robustness of the ON state while surpassing the thermionic limit. We finally comment on other systems like superconducting hybrid systems that rely on Rashba spin-orbit coupling for advanced device functionalities and also a peek into our current ventures on understanding dephasing across topological channels [3].

Talk Title: An insect-inspired collision detector based on atomically thin and light-sensitive 2D memtransistors

Abstract:  Collision detection under poor illumination and nightly conditions pose significant challenge for manned and unmanned vehicles, flying drones, and robots navigating complex terrestrial and extraterrestrial geographies. Existing night vision cameras offer solution based on sophisticated enhancement algorithms or additional thermal sensors necessitating extensive and expensive hardware, which make them power-hungry and untenable for deployment in remote and resource constrained locations. In contrast, nocturnal flying insects can avoid collision using very limited neural resources. Insect-inspired collision detectors based on silicon complementary metal oxide semiconductor technology and field programmable gate arrays also exist, however, the physical separation between sensing and compute and absence of spike-based information processing capability increases their area and energy overhead. Here, we introduce an insect-inspired, spike-based, and in-sensor collision detector using a reconfigurable optoelectronic integrated circuit constructed based on atomically-thin and light-sensitive memtransistors. We imitate the escape response of lobula giant movement detector (LGMD) neuron found in many insect species and demonstrate timely collision detection for various real-life scenarios at night involving cars on collision course. Our collision detector has a small effective footprint of 40 µm2 and consumes miniscule energy of few hundreds pico-Joules.

Talk Title: Use Cost per Ampere delivered ($/ARMS) as a Design Decision Metric for Selecting Power Devices

Abstract:  With many device technologies available today, it is difficult for designers to choose a device using just the data sheet parameters.
Different device technologies have different trade-offs between conduction, switching parameter and thermal performance. Using these parameters to select a device gets complex.
RMS current delivered by a device is a result of the losses generated by it and its thermal performance so, using it to select a device will optimize the choice.
Further, best cost-performance balance can be optimized by comparing cost per Ampere ($/ARMS) delivered using the cost of the devices.
We will present some examples in this paper.

Talk Title: Design, Fabrication, Characterization & Modeling of a 1 GHz RF MEMS resonator for oscillator application

Abstract: The phenomenal accuracy and temperature stability of quartz oscillators has enabled it to rule the frequency control and timing devices market for around 100 years. It may sound ironic that despite quartz being a pure crystalline form of SiO2, it isn’t compatible with the Silicon IC fabrication process. This prevents any possibility of on-chip integration and creates a bottleneck to the size reduction of electronic systems and circuit boards. One solution for this is to replace the quartz crystal with a MEMS based resonator which is CMOS process compatible. In this seminar, I will describe the design, fabrication, characterization and modeling of an RF MEMS resonator operating at around 1 GHz.

Talk Title: Developing a research foundry for quantum systems

Abstract:  Quantum technologies in general and quantum computing (QC) in particular is predicted to be one of the most disrupting among the emerging technologies. Therefore translation of this technology is happening at a neck break speed. As an example, small scale quantum computers are now available as software as a service (SaaS) offered by leading corporates as well as startups. Even though the current backend quantum hardware are too noisy to yield any useful quantum advantage, they are the best playground to explore the potential of quantum computers. Given the complexity of developing a full stack QC, it is essential to develop a library of quantum devices. At the National Quantum Foundry, we develop superconducting circuit chips along with integrated ion traps, photonics circuits and Si-donor qubits.

Abstract:  The terahertz (THz) technology has been experienced rapid advancement in numerous potential applications in the last few years. This includes imaging, communication, material spectroscopy, security, and the bio-medical field. In the first part, a single silicon nanowire (NW) junctionless field-effect transistor (FET) based THz detector will be discussed.

Abstract:  Complementary FET (CFET) is a promising candidate to push CMOS scaling beyond nanosheets and forksheets. CFET is formed by stacking an NMOS and PMOS device on top of each other. Area scaling is achieved by moving the N/P separation from the horizontal plane to the vertical plane. Fabrication of a CFET introduces significant integration challenges as we move away from the conventional processes used for CMOS devices. In this talk, we discuss how to fabricate a CFET (monolithic and sequential), the integration challenges that come with it, and potential areas where innovations are needed to enable this complex device architecture.

Talk Title: NexGen Vertical GaN™ Fin-JFET: Fast Switching and Exceptional Robustness

Abstract:  We present the results of NexGen’s 700V and 1200V normally-off vertical GaN Fin-JFETs. The transistors exhibit small switching losses with no reverse recovery. Switching at 3MHz+ and 1200V is demonstrated. The device can sustain a single-pulse critical avalanche energy density of 10J/cm2 (highest reported in GaN transistors) and >3500 repetitive avalanche pulses. The avalanche current path can be tuned through the gate or the source. The short-circuit withstanding time of 700V Fin-JFETs is 30.5µs at a VBUS of 400V and 11.6µs at 800V, all among the longest reported for 600-700V normally-off transistors. In repetitive 400V/10μs short-circuit tests, Fin-JFETs showed no degradation after 30,000 cycles. These results set a record for GaN transistors and demonstrate equivalent to superior robustness compared to Si and SiC devices.

Talk Title: Reliability aware CMOS neuromorphic circuits

Abstract:  Neuromorphic circuits are gaining popularity due to their application in ANNs. These circuits have low power consumption, better prediction accuracy and are faster than conventional Von-Newman architecture based circuits. The spiking events are really very important in these circuits. Any deviation in spiking may can cause mis communication and led to false prediction. There are certain blocks identified in the neuron circuits which are highly sensitive to degradation. This can cause faulty spiking, positional shift in spiking etc. By mitigating the impact of reliability on those circuit we can minimize the impact of device reliability and hence can make our neuron more reliable.

Talk Title: Impact of Halide Ion Migration on the Stability of Perovskite Solar Cells

Abstract:  The intrinsic ionic defects, specifically halide ion vacancies, often dictate the mobility of halide species within the metal halide perovskite film during the operation of solar cells. Of particular interest is the halide ion mobility in mixed halide perovskites, which offer an insight into the halide ion migration. The origin of processes leading to halide migration is investigated using mixed halide perovskite films. Both hole trapping at I-site and the defect mediated migration influence the mobility of iodide species under photoirradiation. The iodide species migrating toward the grain boundaries render the mixed halide film phase-segregated under photoirradiation. Ways to suppresses the halide ion mobility through introduction of Cs at the A-site will be discussed.

Talk Title: Role of exchange-correlation functionals in migration barrier predictions

Abstract:  A critical factor that influences the rate performance of batteries is the diffusion of the electroactive ions in the active materials, i.e., solid electrodes and/or electrolytes, which in turn is largely influenced by the ionic migration barriers (Em) within host frameworks. Determining Em precisely using experimental techniques, such as electrochemical impedance, variable temperature nuclear magnetic resonance, etc. is not a trivial task. Computationally, evaluating Em is often done via density functional theory (DFT)-based nudged elastic band (NEB) calculations or ab initio molecular dynamics (AIMD) simulations. Typically, DFT-NEB can yield a direct estimate of Em in a given material, while AIMD relies on statistical sampling of migration events (which becomes more difficult with increasing Em values). Hence, DFT-NEB is the preferred computational choice to determine Em. However, the accuracy of DFT-NEB calculations in estimating Em is dependent on the choice of exchange-correlation (XC) functionals, and the errors associated with using different XC frameworks has not been accurately quantified yet. Hence, in the first part of my talk, I will focus on assessing the accuracy of different XC frameworks (versus experiments) in estimating Em in a wide variety of electrode and solid electrolyte materials. Importantly, we find that the strongly constrained and appropriately normed functional yields better accuracy of Em on average, albeit with significant convergence difficulties and notable exceptions of high inaccuracy, while the generalised gradient approximation provides robust qualitative trends in its Em predictions. I will also discuss about the role of uniform background charge and the climbing image approximation in Em predictions.

Talk Title: Significance of Operando Investigations for Understanding the Electrochemical Mechanism of Battery Materials

Abstract:  As far as electromobility is concerned, Li-ion battery (LIB) is at the forefront of current energy storage systems. In a LIB, positive electrode (cathode) is the capacity limiting and negative electrode (anode) is important for determining the safety. In this regard, several electrode materials (anode or cathode) are proposed or developed, those claim to exhibit superior performance in terms of efficiencies, rate capability, discharge capacity, etc. One of the key factors considered during development of novel electrode materials for battery technology is the cost and availability of the elements present. For e.g., Iron and Manganese may be preferred over Cobalt or Vanadium for novel materials as both Co and V are considered less abundant critical elements. Hence, more new materials are expected to be developed in the future and for this operando investigation is extremely important. The talk will give an overview of operando techniques used for investigating battery materials.

Talk Title: Single Layer Substitution Doped Graphene FET: From Numerical Model to Extremely Closed-Form Region-wise Model and Application to Synaptic Plasticity

Abstract:  A phenomenological all region self-consistent drain current model for B/N substitution doped GFET is developed. The effects of B/N doping such as: shift in Dirac points and induced non-zero bandgaps are explicitly captured in this model. However, the self-consistent model only permits numerical solution and it requires precise initial assumption, which makes computationally exhaustive. Hence, a simplified region-wise potential-based analytical model is established for B/N doped GFET. The extreme closed-form analytical nature of region-wise model with computational efficiency makes it highly beneficial to establish a compact model for mimicking the device behavior in circuits. The synaptic devices based on B/N doped GFET have been modeled by utilizing the interface traps to manifest dynamic mimicking of synaptic plasticity.

Talk Title: Laser integrated nanophotonics on an InP membrane

Abstract:  Recent progress in the InP membrane on Si (IMOS) platform will be reviewed. This platform features native laser integration with nanophotonic components on a 300nm thick photonic membrane based on InP material system. The twin-guide active-passive integration strategy enables wafer scale high-density integration of amplifiers and lasers. Large scale nanostructures such as metalens can be realized in the same process flow. Thanks to its high optical confinement, novel materials such as phase change materials can be integrated onto the platform and enable new functions. This technology has high potential for a range of emerging applications including optical wireless communications, non-contact sensing and metrology.

Talk Title: Endeavoring to make a solar battery

Abstract:  Devising energy schemes that merge energy capture with energy storage have gained momentum over the last few years. The impetus stems from utilizing solar radiation efficiently in terms of not only capturing it but also viably storing it in the form of either solar fuels or as electrical storage. The latter technology is still emerging especially in terms of evolving the conceptual idea of directly storing solar radiation as opposed to forming devices that consist of independent batteries/supercapacitors that are separately coupled with solar cells. Hence it can be considered that the integrated system is composed of two kinds of materials: light harvesting and a storage component. Light harvesting component consists of materials that are capable of absorbing light and generating extractable charge carriers, while, energy storage component consists of materials that can trap the charges and store them during periods of illumination, and subsequently release them under discharge conditions.
The talk will present some concepts that are currently available in literature as to how to form such integrated systems and I will also discuss our work where we have used an alternate strategy for coupling energy capture and storage in that the aim has been to create a strategy that minimizes interfaces and so in principle can lead to better performance and charge transport efficiency.

Talk Title: Scaling and device physics of amorphous oxide thin-film transistors

Abstract:  Thin-film transistor (TFTs) channel lengths need to shrink as performance requirements get more demanding for several applications. The switching speed and current drive capability are expected to improve as channel lengths reduce for most field-effect transistors. In many TFTs, contact resistance issues get severe at small channel length. Additionally, the physics of charge transport and basic performance characteristics can change quite substantially at small channel. We will review these properties for amorphous metal oxide TFTs with channel lengths in the range 50 nm – 5 micrometers. A new design for TFTs, based on the use of nanospike electrodes will be presented that greatly mitigates both the contact-resistance problem and short-channel effects as well as reduces DIBL and results in excellent sub-threshold and above threshold characteristics.

Abstract: The key problem with magnetic random access memory (MRAM) is the high current requirement and energy dissipation to write information. This can be solved with electrical field control of magnetization in nanoscale magnets that have the potential to be extremely energy efficient. Our group’s research focuses on using this paradigm towards implementation of energy efficient non-volatile memory [2], neuromorphic computing devices [3] such a quantized synapses and reservoir computers amenable to implement on edge/IoT devices. Furthermore, by tuning the frequency of the such nanomagnet’s electric field drive to the Larmor frequency of spin qubits, single-qubit quantum gates with fidelities needed for fault-tolerant quantum computing [4] can be implemented. These device applications will be discussed.

Talk Title: DNA based electrically readable high-density read only memory array

Abstract: 

We will discuss the concept of an electrically readable memory where the logic states are stored in the resistance of double stranded DNA [1]. These memory elements can in principle be connected to bit and word line nanowires fabricated using DNA origami [2]. We will discuss our effort in modeling the conductance of DNA and the performance metrics of a memory array formed using DNA memory elements. As origami nanowires with a high conductance are yet to be fabricated, we will model the array performance for a variety of interconnect resistances ranging from those of carbon nanotubes to much higher resistances. We will end the talk by discussing the challenges that need to be overcome to realize the proposed memory array.

Talk Title: DTCO for Advanced Technology Device and Circuit Designs

Abstract:  For sub-10 nm technology nodes, the pitch scaling began to slow down, and it is expected to cease as it reaches 1 nm node. To keep the pace of transistor density increments at 45% density increase per node, industry is employing sophisticated Design-Technology Co- Optimization (DTCO) methodologies. Gate All Around FETs (GAAFETs) have been introduced as an advanced to the FinFET architectures, with specific advantages of GAAFETs over FinFETs: i) increased gate control by having the gate all around the channel, and ii) higher transistor density by utilizing the vertical structure with multiple channel regions per fin. In this work, we will analyze the quantum confinement effects due to small cross section of GAAFET channels on the device gate capacitance. To achieve the best possible Power-Performance-Area (PPA) trade-off of logic circuits, need to optimize the 3-D structure of the device for reduced parasitic components. A comprehensive optimization DTCO methodology is required to achieve the target results.

Talk Title: Role of Defects on the Variability of STT-MRAMs and 3D CT NANDs

Abstract:  Spin-transfer torque magnetic RAMs (STT-MRAM) and three-dimensional (3D) charge-trapping (CT) NAND flash devices are considered to be highly prospective for next generation memory and neuromorphic applications owing to their small-footprints, scalability and compatibility with existing CMOS process technologies. Small dimensionalities, as well as inherently stochastic switching characteristics of STT-MRAMs, make these devices significantly prone to device-to-device and cycle-to-cycle variations. The stochastic nature of the charge capture/release processes associated with Program/Erase cycles of 3D CT-NANDs make these devices susceptible to device-to-device variabilities as well. In this work, based on experiments and simulations, the speaker will present recent results pertaining to the role of defects on the variability of memory and neuromorphic related performance metrics of STT-MRAMs and 3D CT NANDs.

Talk Title: High-Capacity Organic Redox Flow Battery

Abstract: To combat global warming, redesigning of the world energy-consuming structure is imminent. India’s solar power tariff has fallen below 3.2¢/kWh, and the international tariff of solar thermal storage power is US$0.063/kWh, which are cheaper than that of fossil fuel plants. Therefore, in the future, solar power cost will become the benchmark for deciding the other fuel prices. Renewables sources are seasonal, therefore there is a requirement for low cost energy storage option to store the excess energy for prolonged time period. Considering the longevity, capacity, availability of raw materials and safety, non-flammable aqueous electrolyte-based redox flow batteries are the choice.

Talk Title: Advances in Silicon Power Semiconductor Devices

Abstract: Silicon power MOSFETs have made tremendous advancements in the past decade. The key concept that has led to this is that of charge balance. In conventional power MOSFET device the maximum doping level and the thickness of the drift region is limited by blocking voltage constraints and a triangular electric field results in its sub-optimal utilization.
The concept of charge balance involves adding an opposite polarity of charge in the drift region compared to default doping to modify the shape of electric field from triangular to trapezoidal for better utilization of drift region for voltage blocking, and allow significantly higher doping concentration for lower conduction losses. For low voltages (below 400V) the popular device structure to achieve this is the Split Gate Transistor (SGT). This device utilizes trench MOS charge balance with a shield electrode under the gate. In addition to significantly improving the On Resistance per unit area (~3x for 100V blocking), the shield electrode also significantly reduced the gate to drain miller capacitance (Crss) and Crss/Ciss ratio to allow for high frequency switching.
For high voltages above 400V, the depth of trench and thickness of liner oxide make SGT device impractical to fabricate. As a result, the Super-Junction transistor has emerged as the most successful MOSFET for high voltages. This device utilizes alternating P and N columns in the drift region thereby creating a charge balance. Methods such as multi epi, deep trench and fill have been demonstrated and are commercially successful for making superjunction transistors. These can achieve an On-Resistance reduction of up to 8x compared to planar DMOS transistor. However, presence of alternating P and N columns also results in peculiar Capacitance curves, particularly the Crss which drops sharply at low drain biases and then increases at higher drain biases. It also exhibits snappy diode reverse recovery.
Charge balanced structure is also finding use in bipolar devices such as IGBT and Fast recovery diodes. In these devices, charge balance is used for various performance enhancements such as improving turn-off losses, injection enhancement, and controlling injection efficiency for faster switching.
The goal of this seminar is to understand the device physics and electrical characteristics of charge balanced devices in unipolar and bipolar power devices. This seminar is intended for intermediate level audience.

Talk Title: A Comparative study of GAN-on-silicon with SiC Devices in the 5KW-10KW Power range

Abstract: GaN-on-Silicon transistors are gaining traction in the field of AC/DC and DC/DC high voltage power electronics for power levels ranging from 45W to over 10kW. Especially in the power levels ranging from 500W to 10kW, bridge topologies such as totem-pole PFC, half-bridge or full bridge converters, inverters etc. are very popular. In this power range, there is always a tussle between GaN-on-Silicon and Silicon Carbide power devices in terms of efficiency and switching frequencies. In the 650V or 900V class of power devices for these power ranges and topologies, it is important to establish the leader in terms of power density, solution temperature and as well as ease of implementation. This paper and presentation provides a direct comparison of leading GaN-on-Silicon devices and its equivalent Rds(on) Silicon Carbide devices in terms of switching characteristics, reverse conduction, reverse recovery, gate driving that can explain the differences in efficiency at various switching frequencies. The quantum effects will not be considered as this paper will focus on experimental results. In the paper, industry’s leading Transphorm GaN-on-Silicon devices will be compared with leading Silicon Carbide MOSFETs.

Talk Title: Heterogeneously integrated InP-laser on Silicon Photonics realized by micro-transfer printing

Abstract: Silicon photonics have gained immense commercial interest in data-center market and soon it will enter other domains as well including biomedical, space applications and so on. Silicon being an indirect bandgap semiconductor efficient lasing cannot be achieved. Therefore, hybrid or heterogeneous integration techniques are normally used to incorporate laser with silicon photonics (SiP) platform. These techniques of integrating lasers on SiP platform are far from ideal in-terms of volume, cost and yield. Micro-transfer printing is an emerging technology which enables massively parallel integration with high yield and hence bring the cost down. In this talk transfer printing of InP-based laser on SiP chip will be presented.

Talk Title: Fully printed, ultra-flexible and low temperature processed oxide electronics

Abstract: Research on printed electronics was initiated with the invention of easy-to-print organic semiconductors in the last century, whereas, it is only about a decade now that printed oxide semiconductors and devices have come up as a possible competitor to this well-matured organic electronics activity. Here, the oxygen deficient n-type oxides can demonstrate carrier mobility close to polycrystalline silicon, and maintain their band transport even when amorphous in nature. In fact, today the dc performance of these solution-processed oxide thin film transistors (TFTs) is no way inferior to their physical vapor deposited counterparts. However, the limited printing resolution has always posed a major hindrance to achieve high operation frequency. In addition, oxides are often criticized for their high process temperatures, and lack of mechanical flexibility. Unsurprisingly, the ceramic oxides are inherently brittle and demonstrate very little (typically <1%) strain tolerance. In contrast, here in this presentation a couple of novel material and (device) design strategies will be discussed that helps to achieve significantly large (up to 5%) strain tolerance under dynamic mechanical test conditions. At the same time, high frequency operation from several tens of kHz to hundreds of kHz will be demonstrated.

Abstract: Millimeter wave (mmWave) communication systems have attracted significant interest regarding meeting the capacity requirements of the future 5G network. Silicon power amplifier (PA) is one of the key challenging components due to high power efficiency and high energy efficiency requirements due to the inherent drawbacks of silicon processes, including low device speed, large losses, low supply, and breakdown voltages, etc. To overcome these issues, power-combining techniques are widely adopted to overcome the power limitation from a single-channel PA. Among different combining techniques, transformer power-combining provides good features such as wide bandwidth and compact size, and therefore is widely adopted. This talk reveals the evolution of mmWave PAs and present the latest power combiner designs.

Indium-Gallium-Zinc Oxide (IGZO), one of many chemoresistive materials, has recently emerged as the best choice due to its unique characteristics such as, high electron mobility (10–100 cm2/(Vs), porous amorphous state, and low growth temperature. This unique properties makes IGZO as a superior candidate for gas detection application. Therefore, to develop high response NO2 gas sensor, this studies focuses on investigation of IGZO thin films sensors under various growth conditions and annealing processes. Thermal annealing techniques such as different ambient, temperature and pressure were systematically explored.

Talk Title: Bipolar lithium-metal battery employing a quasi-solid composite electrolyte

Abstract: Lithium metal is considered as one of the most promising anode candidates for high-energy batteries. However, safety concerns induced by the formation of Li dendrites hinder the practical application. Herein, we report on a thin and flexible hybrid electrolyte composed of Li1.3Al0.3Ti1.7(PO4)3 (LATP), a polymer binder, and a small amount of an ionic liquid-based electrolyte. To reinforce the interfacial stability between LATP and Li, we coat an ultrathin polysiloxane-based single-ion conducting polymer on the lithium surface. This enables a substantial performance improvement of Li‖LiNi0.88Co0.09Mn0.03O2 cells, eventually enabling the successful realization of lab-scale bipolar stacked battery cells.

Talk Title: Understanding Interface Conductivity of Graphene with Oxide Semiconductors

Abstract: Oxide semiconductors are technologically promising for several opto-electronic applications. However, Interface conductivity with the semiconductor has been a major issue due to low electron affinity values of the semiconductor and the identification of a good Ohmic contact will be in the interest of device engineers from diverse fields. Using Cu2O we experimentally measure contact resistance with different metals systematically as well as with graphene, a transparent conducting monolayer. Using first principles calculations we justify the measurements as well as observe that graphene-Cu2O heterojunction work function strongly varies with the atomic configuration of the surface. The oxygen terminated surface of Cu2O is observed to have an Ohmic interface for holes making graphene a good transparent interface for Cu2O based hole transport layers of photovoltaics and photon detectors.

Talk Title: Complex oxide membranes as dielectrics for 2D materials

Abstract: With a rapidly growing family of vdW materials, the role of dielectric and metals have become more important than ever. In this talk, we will present a detailed synthesis, and characterization of various complex oxide nanomembranes as a high-k dielectric. We will present a detailed growth study of SrTiO3 (STO) nanomembranes. Using hybrid molecular beam epitaxy that employs a metal-organic precursor, titanium isopropoxide (TTIP), to supply both Ti and oxygen (without the need for additional oxygen), epitaxial STO films were grown directly on a graphene layer transferred on to bulk STO substrate. Films were then successfully exfoliated and transferred onto other substrates. Using Raman spectroscopy and high-resolution X-ray diffraction, we show that the transferred STO membrane is single-crystalline and can be integrated with other vdW materials.

Talk Title: Modeling of N-polar GaN heterostructures and transistors

Abstract:

N-polar GaN offers significant advantages over Ga-polar GaN. For example, transistors realized with N-polar GaN have demonstrated record values high of power density, operating frequency and record low values of ON-resistance [1]. Most of the modeling efforts have focused on the Ga-polar orientation. We show that the key approximations involved in the modeling of Ga-polar devices need to be revisited while modeling N-polar devices. Based on these observations, we present analytical [2] and closed form models to describe the wavefunctions, surface potential and charge in N-polar heterostructures. We also present an extension of this modeling approach to describe the current-voltage characteristics of N-polar GaN transistors.

Talk Title: An all-electronic true random number generator

Abstract: Generators of random sequences used in cryptographic applications rely on entropy sources for their indeterminism. Physical processes governed by the laws of quantum mechanics are excellent sources of entropy available in nature. However, the read-out from such systems for generating truly random sequences is challenging while maintaining the feasibility of the extraction procedure for real-world applications. I shall present an all-electronic van der Waals heterostructure-based device generating a random sequence with record-high value (>0.98 bits/bit) of min-entropy through the detection of discrete charge fluctuation in a quantum dot embedded in a tunnel junction. The generated high quality random sequence passes tests such as NIST SP 800-90B and NIST SP 800-22.

Talk Title: Multi-scale modeling of devices based on two-dimensional materials heterostructures

Abstract: Atomically thin two-dimensional (2D) material-based devices have emerged as a possible successor of Si nanosheet transistors for future technology nodes. To continue scaling transistors on future technologies, we would need to transition to vertical carrier transport where the gate length does not pose a limitation in reducing the contacted gate pitch.

This talk will discuss the multi-scale modeling technique to design and analyze vertical devices based on 2D materials heterostructures. The multi-scale modeling framework will include the atomistic modeling of vdW heterostructures to understand their electronic properties and vertical electron transport. Further, possible device designs will be discussed using a tight-binding Hamiltonian-based quantum transport framework.

Abstract: In this talk, the challenge and limitation of CMOS scaling will be discussed.
CMOS Scaling has been driven by process integration of new architecture and materials. Continuously scaling and technology innovations, with focus on Front-End-of-Line (FEOL) and Middle-of-Line (MOL) processes, were enabled in the last two decades. Strain engineering and better gate oxide have been improved in early stage to increase device performance, lower supply voltage and leakage. Device architecture from planar to FinFET transistors increases effective width in a given device footprint starting from 14nm technologies. Optimizing Fin material to enhance channel mobility is a challenge. In addition, improving gate to contact pitch over fins and lowering contact resistance are necessary.

Talk Title: Machine Learning Techniques as Alternative to Physics Based Parametric Device Model Development

Abstract: Continuous innovations in the field of semiconductor device architectures are ongoing to meet the growing demands of higher performance, smaller power budgets, and higher frequency of device operation at smaller form factors. Therefore, electronic design automation (EDA) tools have become essential for the timely simulation and analysis of these devices. Current EDA tools entail the solution of the physics partial differential equations related to the electrostatics and charge transport of semiconductor devices using traditional finite-element/finite-difference methods, as in TCAD. Such simulators are extremely time and memory hungry, especially when probing the performance of the device across massively large parameter spaces. In this talk, I will highlight the opportunities presented by emerging machine learning (ML) techniques as extremely efficient alternatives to the standard rigorous physics-based approach for semiconductor devices. Specifically, my talk will focus on the new concept of prior knowledge-based machine learning as a way to enhance the learning ability and trainability of modern ML techniques.

Abstract: Successful demonstrations of STT-MRAM prototypes in recent years have shown promising performance and reliability for embedded non-volatile memory applications.

Talk Title: Heterogeneous integration and chipletization in FPGAs

Abstract: In the post-Moore’s law era, scaling all I/Ps to the next process node is not always the best choice. In recent years, DTCO advancements have helped standard cells in achieving desirable PPA scaling, but SRAM cells and custom blocks have lagged behind. Today’s FPGAs, like AMD Versal® ACAP (Adaptive Compute Acceleration Platform), are using more standard cell logic than ever before, but programmable fabric is still primarily made up of SRAMs and custom layouts. As a result, it is becoming more attractive to adopt some form of chipletization and heterogenous integration to drive future scaling of FPGAs.

Next, I show device-circuit-system co-design and co-simulation of crossbar arrays using these spintronic synapses and demonstrate on-chip learning of fully connected neural networks (FCNNs) and convolutional neural networks (CNNs) through them for image classification.

Talk Title: III-N mm-Wave Transistors for Linearity, Efficiency, and Reconfigurability

Abstract: Achieving the vision and promise of millimeter-wave wireless communication systems (e.g. 6G and beyond) requires significant advancements in device technologies. To obtain the high bandwidths required on a mobile platform, devices offering millimeter-wave performance with low power consumption while simultaneously delivering low noise figure, high linearity, and high power efficiency are essential. Reconfigurability in order to support frequency-agile and compact implementations is also critical. The unique properties of the III-N material system (e.g. polarization, LO phonon mediated electron transport) enable new approaches for designing millimeter-wave transistors for power amplifiers, low-noise amplifiers, and signal switching and routing. The integration of ferroelectrics with III-N transistors also provides opportunities for increased functional density and improved performance in signal switching and routing applications. In this talk, recent advances in these areas will be presented.

Talk Title: Modeling, simulation and applications of engineered TFETs

Abstract: The tunnel field effect transistor (TFET) has drawn considerable attentions for future generation low-power VLSI/ULSI applications due to its extremely low sub-threshold current and good switching characteristics. The TFET possesses low sub-threshold swing below the Boltzmann limit of 60 mV/decade of the bulk MOSFETs. However, the major drawback of the TFET is its very poor ON current. Several techniques have been introduced to improve the performance of the TFETs through various structural modifications. The present talk will introduce the performance analysis of some engineered TFET structures via theoretical modelling and commercially available TCAD simulations. Finally, some applications of the engineered TFETs in the SRAM design and level-free bio-sensors will also be discussed.

Abstract: The discovery of spin-orbit coupling (SOC) in different materials have revolutionized the area of spintronics which relies on both the charge and spin degrees of freedom of an electron. Materials with high SOC can be utilized for efficient transduction between charge and spin currents that can be used for low-power switching of nano-magnetic bits, which will lead to the next-generation spin-orbit torque (SOT) based memory devices. In this regard, a new class of materials called topological insulators (TIs) are the ideal ones for such SOT-based devices because of a near-perfect spin-charge interconversion efficiency achievable on the surface of a TI.

Talk Title: Our Recent Efforts Towards Two Electrode Solar Batteries: Possibilities & Challenges

Abstract: Layered solids are known for their applications in metal ion batteries. In particular, two-dimensional (2D) layered materials are identified as promising candidates for different types of energy devices and optoelectronics. The high surface area and hence the large accessible interaction volume make them suitable for such applications. On another note, new ways of storing solar energy is of high interest due to the importance of renewable energy harvesting and storage. In that context, two electrode solar battery is an emerging concept, where one can store the solar energy directly in to an electrochemical battery storage systems. This solar battery is one having two electrodes but can charge the battery using light without coupling to a solar cell. Some such batteries have shown in the very recent past but their stability for large charge-discharge cycles, mechanism of metal ion battery charging, scalability, efficiency etc are still in question. In this talk, I will be discussing some such issues and our recent efforts in these directions. Our recent findings on an atomic layer, MoS2 for developing a solar battery will be discussed initially.

This brings promises in developing stable solar batteries of high photoefficiency. This idea has been further extended to different other possible battery systems where a battery full cell can be realized. The key findings of those works will be discussed during the talk.

Talk Title: Performance improvement of machine learning hardware accelerators on FPGA

Abstract: CNN accelerators implemented using FPGAs can enable significant performance improvement. To fully utilize the computing capability of an FPGA, there is also a need to efficiently map the design on to the FPGA fabric. We observe that mapping the convolution operation onto pipelined DSP-adder tree (PDAT) structures results in a 2.4× improvement in frequency compared with a default baseline mapping. There is also growing interest in designing flexible FPGA fabrics with alternate physical locations of DSPs and Block RAMs. An initial step is to study the impact of the location of heterogeneous blocks on the performance of the ML benchmarks. We propose a new architecture which consists of clusters of heterogeneous blocks scattered across the FPGA layout. We observe that it results in 6.4% improvement in the critical path delay.

Abstract: Over the last decades, the reliability of GaN-based visible LEDs has vastly improved, mostly due to optimizations in device structure and in the epitaxial growth, to a point where a useful lifetime of the solid-state source in excess of 60 kh can be achieved. For these mature devices, extrinsic events, such as EOS and ESD events, represent a major lifetime-limiting factors during operation. This talk investigates from a physical standpoint the impact of overstress events on GaN-based LEDs, and reports on the device-level mitigation strategies that can be adopted to improve LED robustness against such phenomena.

Talk Title: Low-power Edge Intelligence from an Industry Perspective

Abstract: The world is becoming increasingly connected, from autonomous vehicles, smart homes, personal robotics to space exploration. These AI-powered applications rely on fast, autonomous, near real-time analysis of diverse data from multiple sources. They are pushing the boundaries of computing – taking it closer to the edge, the point where data is collected, and analysed. Neuromorphic computing is expected to play an important role in advancing edge computing capabilities by mimicking the human brain and its cognitive functions such as interpretation and autonomous adaptation. It is a high-performance, ultra-low power alternative to the von Neumann architecture which is based on traditional bus-connected CPU-memory-peripherals. Due to the time and energy required to send information back and forth between the memory and the CPU, von Neumann machines do not have the ability to support the increasing computational power required by AI applications. At the same time, physical limitations in the size of transistor-based processor circuits impact energy efficiency. Evolving neuromorphic processors, which are designed to replicate the human brain, eliminate the von Neumann bottleneck. Inspired by the brain’s adaptability and ability to support parallel computation, neuromorphic devices integrate processing and memory at higher speed, complexity, and better energy efficiency. This is critical for enabling intelligence at the edge and processing sparse events.

Talk Title: Solvating Ionic Liquids to Improve Ionic Transport in PEO-based electrolytes

Abstract: PEO derivatives are currently used as electrolytes for Li metal batteries. Despite their advantages, their conductivity at low temperature is low but can be improved by using ionic liquid as plasticizers. To do so, ionic liquids made of an organic cation and a low coordinating anion are typically used. However, since neither low coordinating anions, nor regular cations interact with the Li+ cation, the fraction of the current effectively transported by Li+ is low. Thus, we propose the use of more coordinating anions or even solvating cations to improve ionic transport. This approach not only allows improving Li+ transport, but also the transport of divalent ions such as Ca2+ as investigated within the VIDICAT project (EU: 829145).

Talk Title: Key Components of Contact Resistance to Atomically Thin Semiconductors and Requirements for Their Reduction

Abstract: Achieving good electrical contacts is one of the major challenges in realizing devices based on atomically thin two-dimensional (2D) semiconductors. Several approaches have been proposed to reduce contact resistance, including clean contacts, doping, phase engineering, edge contacts, 2D contacts, van der Waals (vdW) contacts, and semimetal contacts. Nonetheless, a better understanding of the fundamental mechanisms limiting the electrical contact resistance to atomically thin 2D semiconductors is needed. This talk will revisit the classical transmission line model description of contacts to 2D materials, present experiments and simulations that uncover the key components of contact resistance to 2D semiconductors and provide guidelines for their reduction. The presented findings can explain recently published state-of-the-art results and offer insight for future contact engineering.

Talk Title: Logic-in-Memory Based on an Atomically Thin Semiconductor

Abstract: Machine learning and signal processing on the edge are poised to influence our everyday lives with devices that will learn and infer from data generated by smart sensors and other devices for the Internet of Things. The next leap towards ubiquitous electronics requires increased energy-efficiency of processors for specialized data-driven applications. I will present here how we realised an in-memory processor fabricated using a two-dimensional materials platform can potentially outperform its silicon counterparts in both standard and non-traditional Von Neumann architectures for artificial neural networks. The circuits are based on a flash memory array with a two-dimensional channel using wafer-scale MoS2. Simulations and experiments show that the device can be scaled down to sub-μm channel length without any significant impact on its memory performance.

Talk Title: Breaking the Light Outcoupling Efficiency Limit in Perovskite Quantum Dots LEDs Featuring Anisotropic Nanocrystals Superlattices

Abstract: Colloidal lead halide perovskites (LHPs) are emerging as one of the most promising classes of light-emitting semiconductors for next-generation displays. However, their intrinsic light outcoupling efficiency remains considerably lower than the organic counterpart, because it is not yet possible to control the transition-dipole-moment (TDM) orientation in QD solids at the device level. Here, we obtain horizontal TDM orientation in the individual anisotropic nanocrystal (ANC) that remains intact in the ANC superlattice (ANSL) without influencing the photoluminescence quantum yield (PLQY) by controlling the aspect ratio of ANCs. Our optimized perovskite light emitting diodes (LEDs), comprising ANSLs thin films with near-unity PLQY, showed record high external quantum efficiency of ~25% and a current efficiency of 103 cd/A.

Talk Title: Development of passive matrix displays based on thermo- and electro-chromic materials

Abstract: Flexible, lightweight, and low-power displays are an active area of interest in the electronics community. In this talk, I will focus on our group’s work on developing displays based on thermochromic and electrochromic materials. Thermochromic materials are those that change colour due to a change in temperature. By combining with silver nanowires, we have synthesized printable inks that can change colour, mediated by Joule heating. An additional touch functionality can be enabled by encapsulating these materials and some prototypes will be highlighted. Electrochromic materials show a colour change by a change in oxidation state. Typically, transition metal oxides are used for these applications. I will highlight our group’s work in developing nickel and tungsten oxide films, through low temperature processing routes, for electrochromic displays.

Talk Title: Hybridization in Plasmonic Devices: a path to outperform their Si Counterparts

Abstract: For integrated optical devices and resonators, realistic utilization of the superior wave-matter interaction offered by plasmonics is typically impeded by Ohmic loss, which increase rapidly with mode volume reduction. Although coupled-mode plasmonic structures have demonstrated effective alleviation of the loss-confinement trade-off, stringent symmetry requirements must be enforced for such reduction to prevail. In this work, we report an asymmetric plasmonic waveguide that is not only capable of guiding subwavelength optical mode with long-range propagation, but is also unrestricted by structural, material, or modal symmetry. In these composite hybrid plasmonic waveguides (CHPWs), the versatility afforded by the coupling dissimilar plasmonic modes allow better fabrication tolerance and provide more degrees of design freedom to simultaneously optimize various device attributes. Specifically, experimental realization of CHPW demonstrates propagation loss and mode area of only 0.03 dB/μm and 0.002 μm2 respectively, corresponding to the smallest combination amongst long- range plasmonic structures reported to-date. As these waveguide attributes are robust over large process conditions and optical bandwidth, CHPW ring resonator with 2.5 μm radius has been realized with record Purcell factor compared to existing plasmonic and dielectric resonators of similar radii.
Using this platform, record experimental attributes such as normalized Purcell factor approaching 104, 10-dB amplitude modulation extinction ratio with <1 dB insertion loss and fJ-level switching energy, and photodetection sensitivity and internal quantum efficiency of -54 dBm and 6.4 % respectively have been realized within our amorphous-based, CHPW. The ability to support multiple optoelectronic phenomena while providing performance gains over existing plasmonic and dielectric counterparts offers a clear path towards reconfigurable, monolithic plasmonic circuits.

Talk Title: Temperature Dependent Band Gaps and Giant Excitonic Binding Energies in Novel 2D beta-phase Nitrogen Arsenide and Nitrogen Antimonide

Abstract: We present a detailed study of the electronic and optical properties of two new monolayer materials, nitrogen arsenide NAs, an nitrogen antimony NSb in their beta-phases. We used a combination of advanced many-body techniques to study electron−electron, electron−hole, electron−phonon, and even exciton−phonon interactions, leading to unique descriptions and deciphering of extraordinary properties of materials under investigation. Both wide-gap semiconductors, NAs and NSb (indirect quasiparticle gap ∼4.5 and ∼3.7 eV, respectively), embody strong exciton binding energies, ∼1.6 and ∼1.4 eV, respectively. In opposite, finite-temperature optical absorption in NSb is quite resilient to the temperature variations. We further proved that even a small tensile biaxial strain stabilizes with no loss in absorbance spectra; therefore, the practical preparation of them on support or included in heterostructures is possible.

Talk Title: Electromechanical oscillators from Mott memristors

Abstract: Neurons are electromechanical systems, which communicate with sound signals which are coupled to electronic signals. Cell membrane of pig neurons, for e.g., undergoes a phase transition from solid to gel phase, and operating them across the phase transition is responsible for such a behavior. In this talk I will show that an electromechanical oscillator can be designed from Mott memristors (epitaxial VO2 thin film samples) which exhibit an insulator to metal and associated structural phase transitions. For the first time, we show that the mechanical oscillations are throughly coupled to current oscillations in our two terminal devices, which are both related through temperature oscillations occuring the same frequency. I’ll comment about the possible isentropic and dissipationless features of these oscillations. In addition, by adding an L||C in series with these devices, we can experimentally emulate a Chua’s circuit that can generate chaos, and demonstrate electromechanical tonic bursting behavior of our samples, in addition to non-linear yet periodic oscillations. That we are able to demonstrate two different types of neuronal behavior from one memristor device is novel.

Recently-developed EOM devices show EO bandwidths above 100 GHz, require only a few volts of RF drive, have a low optical loss of about 1 dB, and support more than 100 mW laser power. We also discuss a class of EOM-based switches where extremely low loss and high speed are necessary for quantum photonics and have been recently achieved. We discuss how modern EOM devices achieve design scalability and industrial manufacturability through several TCAD techniques, including heterogeneous materials integration and just-in-time mask definition.

Abstract: Selected biochemical variables are subject to rapid change in the body and justify continuous monitoring. We developed sterilized tissue implantable O, glucose and lactate needle electrodes for short term use. Membrane capping and enzyme (glucose/lactate oxidase) functionalization allowed reliable monitoring with presented a quite distinct physiological compartment with local blood flow overriding circulatory changes in pO2 during exercise, glucose demonstrating a dynamic lag and recovery and lactate subject to a tissue-blood barrier.

Talk Title: Trapping effects in High-Power 4H-Silicon Carbide (4H-SiC) Bipolar PiN Rectifiers

Abstract: Silicon carbide (4H-SiC) PiN diodes demonstrated ultra-high breakdown voltage (VBR < -10 kV) and extremely low reverse leakage current. The PiN rectifiers benefit from the drift conductivity modulation due to the minority carrier injection process, which mitigates the high-resistance of the voltage blocking layer. Nevertheless, performance limiting defects (Z1/2 and EH6/7) commonly exist in the drift layer. Additional trap levels are created in the epilayer during the Al-ion-implantation process. These traps restrict the maximum achievable performance of the PiN diodes.
The talk describes the identification of electrically active traps in the PiN diodes by Deep Level Transient Fourier Spectroscopy (DLTFS). The charge trapping induced changes in the current handling capability, on-resistance, leakage current and breakdown voltage of the PiN rectifiers are presented.

Talk Title: Programmable Silicon Photonic Circuits

Abstract: Programmable photonic circuits are chips that manipulate light, and where the flow of light can be configured through a layer of electronics and software. This contrasts strongly with most photonic chips today, which have a fixed flow of light, custom-designed for one application. Programmability on a photonic chip means that the connectivity and functionality can be reconfigured, or even completely synthesized at run time. This is reminiscent of field-programmable gate arrays (FPGA) or digital signal processors (DSP) used in digital electronics. We discuss the basic photonic technology blocks for programmable photonic circuits, and the technological layers around these chips to make them programmable. The programmability in itself significantly lowers the threshold to experiment with photonic circuits, and could accelerate adoption and application developments.

Talk Title: Gate-All-Around Nanosheet Device Options for Multi-Node Extendibility

Abstract: We investigate nanosheet family of devices for logic CMOS scaling at 3nm and beyond using full design-technology co-optimization framework. FinFETs, gate-all-around (GAA) nanosheets (NS)-FETs and fork-sheets (FS)-FETs options are benchmarked. While GAA NS provide better performance and gate-length scaling than FinFETs, additional process optimization by decoupling inner- and outer-gate lengths can result in added gate-length scaling flexibility. Impact of vertical pitch is further investigated, especially considering impact of work-function mismatch between inner- an outer-gates at aggressively scaled vertical pitch. It is observed, that up to 200meV work-function difference between inner-outer gates, devices still perform better at 11nm pitch as compared to 15nm pitch.

Talk Title: Towards extreme scaling of CMOS technology using Forksheet and CFET

Abstract: Scaling below 3nm will bring us far into the post FinFET era where extremely scaled logic standard cell heights and SRAM will limit the nanosheet scalability. The novel forksheet device architecture has been proposed as an ultimate scaling device towards 2nm and beyond. Furthermore, complementary FETs (CFETs) offer promise of ultimate scaling beyond the 1nm node and the ability to integrate alternate high mobility channels. Beyond CFETs, 2D materials such as MoS2, WS2 or HfS2 can be used to form atomic channel transistors, offering high mobilities and gate length scaling potential.

Abstract: The disinfection industry would greatly benefit from efficient high-power deep-ultraviolet light-emitting diodes (UV-C LEDs). In this talk, I discuss progress in the growth and fabrication of AlGaN LEDs on SiC Substrates. First, we will discuss the physics of lighting with double heterostructures LEDs and the physics of nitride semiconductors. 

Then I will discuss the development of epitaxial growth and processing techniques for the best demonstration of UV LEDs (260—275 nm ) on SiC substrate, which was enabled by novel thin-film flip-chip processes and resulted in high LED light extraction efficiency relative to planner sapphire or AlN substrates. Moreover, I will discuss tunnel junction UV LEDs and how they can significantly improve LED performance and the potential of UV disinfection.
