Boron-doping controlled peculiar transport properties of ...
2013-1-1 · The Boron-doping in center of graphene ribbon [16,17] weakly influence electron transport property of our p–n junctions and we mainly discuss the Boron-doping at the edge of graphene nanoribbon. The result of Ref. [15] shows that the edge Boron-doped ZGNR has the largest energy gap when the interval of Boron-doping is two ZGNR periods.
