Observation of the relativistic response of an electron-hole plasma in graphene on femtosecond timescales

Visible pump-probe spectroscopy isolates the femtosecond Drude response of a photo generated electron-hole plasma in monolayer graphene. The observed VN scaling versus carrier density reveals the relativistic nature of the electron-hole plasma.
