Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride
06 Dec 2018 | | Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan
Graphene is a zero-bandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (h-BN) opens a bandgap in the band structure of...
