摘要：
In this work, the electronic transport in armchair graphene nanoribbons in the presence of surface corrugation is studied. The non-equilibrium Green's function along with tight-binding model for describing the electronic band structure is employed to investigate the electronic properties of graphene nanoribbons. The effects of surface corrugation parameters, such as corrugation amplitude and correlation length, on the electronic properties of the graphene nanoribbons are studied. The mean free path of carriers is extracted and its dependency on the corrugation amplitude and correlation length is investigated. (C) 2013 AIP Publishing LLC.
