Exact Results for Intrinsic Electronic Transport in Graphene
Source PublicationCHINESE PHYSICS LETTERS
Language英语
AbstractWe present exact results for the electronic transport properties of graphene sheets connected to two metallic electrodes. Our results obtained by transfer-matrix methods are valid for all sheet widths and lengths. In the limit of the large width-to-length ratio relevant to recent experiments, we find a Dirac-point conductivity of 2e(2)/root 3h and a sub-Poissonian Fano factor of 2 - 3 root 3/pi similar or equal to 0.346 for armchair graphene; for the zigzag geometry they are respectively 0 and 1. Our results reflect essential effects from both the topology of graphene and the electronic structure of the leads, giving a complete microscopic understanding of the unique intrinsic transport in graphene.
