Intrinsic carrier mobility of a single-layer graphene covalently bonded with single-walled carbon nanotubes

We report intrinsic carrier mobility calculations of a two-dimensional nanostructure that consists of porous single layer graphene covalently bonded with single-walled carbon nanotubes on both sides. We used first-principles calculation and found that the deformation potential of such system is about 25% of that of graphene, and the carrier mobility is about 5 x 10(4) cm(2) V-1 s(-1) for both electrons and holes, about one order of magnitude lower than that of graphene. This nanostructure and its three-dimensional stacking could serve as novel organic electronic materials. (C) 2014 AIP Publishing LLC.
