Observation of an intrinsic bandgap and Landau level renormalization in graphene/boron-nitride heterostructures.

Abstract

Van der Waals heterostructures formed by assembling different two-dimensional atomic crystals into stacks can lead to many new phenomena and device functionalities. In particular, graphene/boron-nitride heterostructures have emerged as a very promising system for band engineering of graphene. However, the intrinsic value and origin of the bandgap in such… (More)
