## Abstract We perform __ab initio__ calculations for graphene nanoribbons (GNRs) using density‐functional 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
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 sðE F Þ displays four different types of behavior, classified to different regimes of length scales decide
