Conductance of Graphene Nanoribbon Junctions and the Tight Binding Model
In order to simplify the problem of charge transport within graphene-based electronic devices most simulations assume an energy band structure based on a nearest-neighbour tight binding analysis. In this paper, we report for the first time significant differences in the conductance of graphene nanoribbons and metal/semiconductor junctions when using a third nearest-neighbour tight binding analysis in conjunction with an efficient nonequilibrium Green’s function formalism. The results enable more accurate design of graphene based transistors.
