摘要
Quantum transport properties of mono-bi-monolayer graphene junctions (MBMGJs) are investigated via first principle calculation. The simulation results show that the MBMGJs introduce more effective quantum transport channels in comparing with a full monolayer graphene nanoribbon channel and result in significantly increased on-state current. An overlapping-MBMGJ channel with one overlapping zigzag carbon chain shows a larger current even than a full bilayer graphene channel. The robustness of the effective quantum transport channel introduced by the overlapping-MBMGJ against the variation of the length of the bilayer region is also verified. (C) 2013 AIP Publishing LLC.
