Abstract

We report the study of the helicity-driven photocurrents in graphene excited by midinfrared light of a CO₂ laser. Illuminating an unbiased monolayer sheet of graphene with circularly polarized radiation generates— under oblique incidence—an electric current perpendicular to the plane of incidence, whose sign is reversed by switching the radiation helicity. We show that the current is caused by ...
