In this talk, Dr. Lee will describe novel transport properties that arise in two‐dimensional (2D) materials, including graphene and other 2D van der Waals (vdW) materials. These properties may not lead to anything useful. But the experimental realizations of these properties are new, even though they had been predicted theoretically decades ago. The first part of the talk will be about counterintuitive transmission of relativistic particles through a potential barrier known as the Klein paradox, which we could not demonstrate in a condensed matter system until the discovery of graphene. The second part of the talk will be about the formation of Schottky barriers at a vdW interface.
