Topic: “Nanoscale III-V Electronics: InGaAs FinFETs and Vertical Nanowire MOSFETs”

Abstract:
In the last few years, as Si electronics faces mounting difficulties to maintain its historical scaling path, III-V compound semiconductors, in particular InGaAs, have received a great deal of attention. Sub-10 nm CMOS applications require a 3D transistor geometry. In this regard, the vertical nanowire (VNW) MOSFET represents the ultimate scalable transistor. The gate-all-around nanowire configuration allows for the greatest degree of charge control in the channel. The vertical transport direction uncouples footprint scaling (on the plane of the wafer) from gate length scaling (normal to the wafer) leading to the best possible combination of transistor density and short-channel effects.
At MIT, we are investigating vertical nanowire InGaAs MOSFETs and FinFETs fabricated by a top-down approach. Towards this goal, we have developed Reactive Ion Etching technology for In-containing III-V compounds that yields high aspect ratio structures with vertical and smooth sidewalls. We have also perfected digital etch to controllably thin down fins and vertical nanowires to below 10 nm width/diameter. Using these technologies, we have demonstrated InGaAs VNW MOSFETs and FinFETs with sub-10 nm critical dimensions. In both families of transistors, we have obtained promising electrical characteristics. This talk will review these recent developments, put them in context of the overall progress of Si CMOS and outline the prospects and challenges of III-V transistors for future nanoscale logic.

Topic: “2D Materials for Smart Life”
Abstract:
Two-dimensional (2D) materials such as graphene and various transition metal dichalcogenides (such as MoS2) possess a wide range of remarkable properties that make them attractive for a number of applications, including sub-10 nm VLSI. I will highlight the prospects of 2D materials for innovating energy-efficient transistors, sensors, interconnects and passive devices targeted for next-generation electronics needed to support the emerging paradigm of the Internet of Things (IoT). More specifically, I will bring forward a few applications uniquely enabled by 2D materials and their heterostructures that have been demonstrated in my lab for realizing ultra-energy-efficient electronics. This will include the world’s first Kinetic Inductor that exploits a low-dimensional material property of graphene to overcome a 200 years old limitation of the conventional Faraday-inductor and opens up a new pathway for designing ultra-compact IoT systems (Nature Electronics 2018), a 2D-channel band-to-band tunneling transistor that overcomes a fundamental power consumption challenge in all electronic devices since the invention of the first transistor (Nature 2015), the first 2D FET based biosensor with unprecedented sensitivity (ACS Nano 2014), as well as a breakthrough interconnect technology based on doped-graphene-nanoribbons, which overcomes the fundamental limitations of conventional metals and provides an attractive pathway toward an energy-efficient and highly reliable interconnect technology for next-generation integrated circuits (Nano Letters 2017). I will also discuss the prospects of monolithic 3D integration with 2D materials for realizing 3D ICs of ultimate thinness and integration density.

Topic: “Near-Zero-Index Photonic Materials and Devicesc
Abstract:
Metamaterials and metasurfaces have enabled scientists and technologists with unique tools to tailor and manipulate waves in unconventional ways, providing novel platforms with unprecedented wave physics and engineering for photonic materials, optical devices and components. One such platform is the near-zero-index photonics. In such media, the effective relative permittivity and/or relative permeability is engineered to be very low (i.e. near zero) at the operating frequency, which leads to the near-zero effective refractive index. As a result, in such epsilon-near-zero (ENZ), mu-near-zero (MNZ), and/or near-zero-index (NZI) structures the wavelength is “stretched”, and consequently the phase distribution is effectively uniform throughout the structure’s volume. A variety of unique phenomena including supercoupling, photonic doping, electric levitation, extreme quantum optics, thermal beaming, and giant nonlinearity is exhibited in such platforms. In this talk, I will present an overview of some of our results in these areas, and will discuss some of their potential applications.

Topic: “Metal Halide Perovskites at the Nanoscale: high quality optoelectronic materials with unique phase properties”
Abstract:
The newly rediscovered perovskite semiconductor system has the potential to be extremely transformative for all optoelectronic devices, especially photovoltaics (PVs). Perovskite semiconductors of the form APbI3 where A is a large +1 charged cation, typically Cs, methylammonium, or formamidinium have had a huge resurgence among materials scientists for outstanding PV properties despite being overlooked for decades. Semiconductors containing the latter two A-site cations listed are hybrid organic-inorganic materials, and as such, are far less understood compared to conventional all inorganic or even organic material systems. Regardless of this spotty formal understanding, lead-halide perovskites have very rapidly been optimized to power conversion efficiency levels on par with all other materials even with extensive history of research. Perovskites show a unique tolerance to crystalline defects that cause trouble in most other semiconductors. Therefore the potential offered is that very high efficiency PVs can be fabricated in extremely fast and inexpensive ways, thus offering a revolution for the solar industry and a direct route toward producing the world’s energy with a simple and clean technology. Long-term durability of the devices is the critical remaining challenge to be solved.1 Two examples of major instabilities in device performance are the volatility of the organic cation and the specific crystal habit in which the material embodies.
Nanoscale versions (often termed quantum dots (QDs)) of the all-inorganic metal halide perovskite (CsPbI3) tend to retain the desired cubic phase due to strain effects at the surface of the QDs whereas conventional films of the same material “relax” to an orthorhombic structure at room temperature. Therefore these QDs potentially solve both of the instability issues. The cubic CsPbI3 QD cells operate with a rather remarkable open-circuit voltage of >1.2 volts and have produced power conversion efficiencies over 13%.2,3 This customizable new nanomaterial system has incredible potential for many applications in optoelectronics, including photovoltaics, LEDs, displays and lasers. We describe the formation of α-CsPbI3 QD films with long range electronic transport that retain the high temperature phase in ambient conditions making up the active layer in optoelectronic devices. Perspectives on how this technology can become transformative will be discussed.
