Current Quantization in Corrugated Graphene Nanoribbons
ORAL
Abstract
Corrugated graphene provides such a phenomenon as curvature induced $p-n$ junction band gap opening and decoherence. We report yet another effect of current quantization in graphene nanoribbons via energy minigaps induced by the corrugation. Effects of edge roughness and long range charged scatterers on the quantization are investigated. Comparison is drawn with acoustically induced minigaps in carbon nanotubes [Talyanskii et al.,PRL 87,276082(2001)].
