The aim of the workshop is to bring together a leading group of researchers, in addition to students, postdocs and other participants, to discuss 2D platforms for spin, valley, and topological physics and their potential applications. With the continued evolution of graphene spintronics, combined with the recent advances in spin/valley-polarized excitations in transition metal dichalocogenides, and novel concepts related to the theory and synthesis of emerging new materials, there is a critical mass of researchers with complementary interests. In addition, monolayer magnetism and robust 2D topological states are important challenges moving forward. At this workshop, participants will bring expertise from a variety of disciplines and discuss the latest advances in this growing field. This workshop is supported by the Center for Emergent Materials (CEM) an NSF Materials Research Science and Engineering Center (MRSEC), the Institute of Complex and Adaptive Matter (ICAM), the Institute for Materials Research (IMR), and the Center for Exploration of Novel Complex Materials (ENCOMM).
Registration is limited to the first 40 registrants for each session.

Webinar: Nanometer Scale III-V CMOS, sponsored by the IEEE EDS/Photonics Chapter Distinguished Lecturer Program
In the last few years, as Si electronics faces mounting difficulties to maintain its historical scaling path, transistors based on III-V compound semiconductors have emerged as a credible alternative. To get to this point, fundamental technical problems had to be solved though there are still many chal-lenges that need to be addressed before the first non-Si CMOS technology becomes a reality. Among them, harnessing the out-standing electron transport properties of InGaAs, the leading n-channel material candidate, towards a high-performance na-noscale MOSFET has proven difficult; contact resistance, offstate characteristics, reliability and Si integration remain serious problems. Introducing a new material system is not the only challenge. Scalability to sub-10 nm gate dimensions also demands a new 3D transistor geometry. InGaAs FinFETs, Trigate MOSFETs and Nanowire MOSFETs have all been demonstrated but their performance is still disappointing. To compound the challenge, a high-performance nanoscale p-type transistor is also re-quired. Among III-Vs, InGaSb is the most promising candidate. Planar MOSFETs have been demonstrated but more advanced geometries remain elusive. This talk will review recent progress as well as challenges confronting III-V electronics for future CMOS logic applications.

Description: In this talk I will discuss the current work in my group on developing surfaces with extreme wettabilities, i.e. surfaces that are either completely wet by, or completely repel, different liquids. The first portion of the talk will cover the design of so called “superomniphobic surfaces” i.e. surfaces which repel all liquids. Designing and producing textured surfaces that can resist wetting by low surface tension liquids such as various oils or alcohols has been a significant challenge in materials science, and no examples of such surfaces exist in nature. As part of this work, I explain how re-entrant surface curvature, in addition to surface chemistry and roughness, can be used to design surfaces that cause virtually all liquids, including oils, alcohols, water, concentrated organic and inorganic acids, bases, solvents, as well as, viscoelastic polymer solutions to roll-off and bounce.
The second portion of my talk will cover the design of the first-ever reconfigurable membranes that, counter-intuitively, are both superhydrophilic (i.e., water contact angles @ 0°) and superoleophobic (i.e., oil contact angles > 150°). This makes these porous surfaces ideal for gravity-based separation of oil and water as they allow the higher density liquid (water) to flow through while retaining the lower density liquid (oil). These fouling-resistant membranes can separate, for the first time, a range of different oil–water mixtures, including emulsions, in a single-unit operation, with >99.9% separation efficiency, by using the difference in capillary forces acting on the oil and water phases. As the separation methodology is solely gravity-driven, it is expected to be one of the most energy-efficient technologies for oil-water separation.
I will also discuss surfaces with patterned wettability, where both wetting (omniphilic) and non-wetting (omniphobic) domains are fabricated on the same substrate. We use such substrates for fabricating monodisperse, multi-phasic, micro- and nano-particles possessing virtually any desired composition, projected shape, modulus, and dimensions as small as 25 nm. Finally, I will discuss some other areas of current and future research, including the development of ice-phobic coatings that offer one of the lowest reported adhesion strengths with ice.
