Time-resolved photoconductivity of graphene films is detected (see image). The graphene films are prepared through the reduction of graphene oxide. Under different incident light intensities, external electric fields, photon energies, and preparation methods of the films, photocurrent generation efficiency and decay time of these graphene-based films are compared and discussed.
