Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride

Published on

Abstract

  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 graphene. Using DFT Material Properties Simulator in nanoHUB, the band structure of the bilayer and bulk system of graphene and h-BN is presented. Based on the density of states (DOS) data, the bandgap opening is obtained. The band structure of different alignment between graphene and h-BN layers is calculated. Using LanTrap, electron thermal conductivity of this material is investigated.
