We investigate the conductivity s of graphene nanoribbons with zigzag edges as a function of Fermi energy E F in the presence of the impurities with different potential range. The dependence of sΓ°E F Γ displays four different types of behavior, classified to different regimes of length scales decide
We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-binding model and calculate the density of states and the conductance within the Green's function formalism based on rea
## Abstract We perform __ab initio__ calculations for graphene nanoribbons (GNRs) using densityβfunctional theory (DFT) and generalized gradient approximation (GGA) functionals. We present results for the dependence of the band structures and energy gaps on the ribbon widths for armchair and zigzag
