## 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
Graphene is a perfectly two-dimensional single-atom thin membrane with zero bandgap. It has attracted huge attention due to its linear dispersion around the Dirac point, excellent transport properties, novel magnetic characteristics, and low spin-orbit coupling. Graphene and its nanostructures may h
