Band-structure topologies of graphene: Spin-orbit coupling effects from first principles

The electronic band structure of graphene in the presence of spin-orbit coupling and transverse electric field is investigated from first principles using the linearized augmented plane-wave method. The spin-orbit coupling opens a gap of $24\text{ }\ensuremath{\mu}\text{eV}$ (0.28 K) at the $K({K}^{... View More
