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 nanometer-scale electronic structure of graphene and related materials.
