Scanning Tunneling Microscopy of Graphene on a Boron Nitride Substrate

ORAL

Abstract

Graphene placed on a boron nitride (BN) substrate has been shown to result in increased mobility and improved Quantum Hall measurements.\footnote{Dean, CR \textit{et al.} Boron nitride substrates for high-quality graphene electronics. \textit{Nature Nanotechnology} \textbf{5}, 722-726 (2010)} It is therefore of great interest to understand how BN substrates differently influence graphene compared to more standard SiO$_{2}$ substrates. I will present new scanning tunneling microscopy measurements of graphene placed on a BN substrate. Differences in the local behavior of graphene on a BN substrate versus a SiO$_{2}$ substrate will be discussed.
