Carrier density and light helicity dependence of photocurrent in mono- and bilayer graphene
Helicity-dependent photocurrent in monolayer graphene has been the subject of intense debate, and was recently ascribed to photon drag and circular photogalvanic effects. Unlike inversion symmetric monolayer graphene with no band gap, the most stable case of two-layer graphene, AB-stacked bilayer gr...
