Abstract

Graphene, an atomically thin sheet of hexagonally oriented carbon, is a zero band gap semi-metal that exhibits extraordinary electronic and optical behavior. Hexagonal boron nitride, which shares a similar structure to that of graphene, is an insulator that does not absorb any light in the visible spectrum. By combining graphene and boron nitride into ultrathin vertical stacks, we fabricated new optoelectronic devices that demonstrate highly sensitive optical response, yet are only several nanometers thick. In this talk, I will discuss how stacking these atomically thin materials allows us to explore new types of optoelectronic devices that reveal a novel hot carrier transport regime, which may lead to more efficient energy harvesting technologies.
