Abstract

Cu/graphene contact is the key interface for graphene- based devices. In the paper, first-principle calculations are used to investigate the detailed interface atomic and electronic structures and Mulliken charge populations of monolayer, bilayer, trilayer grapheme/Cu (111) interface. The Fermi level is pining by the Cu substrate and shifts due to the n-type doping of graphene.
