概要

• 論文の詳細を見る

• We have investigated the electron transport properties of zigzag graphene nanoribbons (GNRs) connected to one-dimensional leads on the edge. Transport properties are calculated using the nonequilibrium Green’s function method with a tight-binding scheme. We revealed that an edge current originating in the edge states exists and found that the half width of the resonant peak of the transmission spectrum decays exponentially with increasing width of the GNR.
