New Materials for Nanoelectronics: A View from the Bottom

Abstract

This century has seen the end of Moore's Law and a consequent explosion of interest in new materials for electronics. A central theme has been the control of electronic structure and transport properties through constraints of dimensionality and—more recently—topology. The catalyst for this growing research in 2D and topological materials was the development of graphene; with Georgia Tech playing a leading role. In this talk, I will discuss some of the ideas behind nanoelectronic applications of 2D and topological materials, and I will present scanning tunneling microscopy and spectroscopy methods that we have developed for determining the nanometerscale electronic structure of graphene and related materials.
