Abstract: We report a first-principles based study of mesoscopic quantum transport inchemically doped graphene nanoribbons with a width up to 10 nm. The occurrenceof quasibound states related to boron impurities results in mobility gaps aslarge as 1 eV, driven by strong electron-hole asymmetrical backscatteringphenomena. This phenomenon opens new ways to overcome current limitations ofgraphene-based devices through the fabrication of chemically-doped graphenenanoribbons with sizes within the reach of conventional lithography.
