▎ 摘  要

We analyze the possibility of optical generation of charge and spin currents in graphene by light carrying an orbital angular momentum (OAM). The graphene is assumed to be deposited on a substrate that induces Rashba spin-orbit coupling. In addition, a weak external magnetic field is assumed to be applied in the plane of graphene. We show that the photon absorption and the magnitude of the generated charge and spin currents depend remarkably on the parameters characterizing the light with OAM. Published by AIP Publishing.
