Photo-induced Modulation Doping in Graphene/Boron Nitride Heterostructures

ORAL

Abstract

Van der Waals heterostructures (VDH) allow a modular platform for materials engineering, where various layered materials with different electrical, optical, and mechanical properties can be stacked together to enable new physics and novel functionalities. To create various VDH, we have employed a ``stamping transfer'' [1] in which two layered materials are exfoliated on separate substrates and then stamped onto each other. Several distinct VDH structures have been realized and characterized through scanned probe and optical measurement schemes. I will discuss recent progress made on these efforts, with an emphasis on optoelectronic measurements of a Graphene/Boron Nitride VDH.\\[4pt] [1] Zomer, P. J. and Dash, S.
