Abstract :
We report the results of a multi-scale transport modeling of ultra-narrow GNRs. Atomistic NEGF approach is combined with semiclassical mobility modeling in order to quantify the sensitivity of mobility to edge defects. We find that the mobility in defected GNRs deteriorates more strongly as GNR width is scaled down compared to ideal devices, and that even the minimum mobility variation spans almost one order of magnitude.
