Intrinsic Spin-Orbit Coupling in Zigzag and Armchair Graphene Nanoribbons
Starting from a tight-binding model, we derive the energy gaps induced by intrinsic spin-orbit (ISO) coupling in the low-energy band structures of graphene nanoribbons. The armchair graphene nanoribbons may be either semiconducting or metallic, depending on their widths in the absence of ISO interac...
