Abstract: Interfacing light-sensitive semiconductors with graphene can afford high-gain phototransistors by the multiplication effect of carriers in the semiconductor layer. So far, most devices consist of one semiconductor light-absorbing layer, where the lack of internal built-in… read more here.

Abstract: It has been shown experimentally that an electron-hole plasma forms in the surface layer at a depth of ~30 nm, followed by a transition to the metallic state, when GaAs is exposed to femtosecond laser… read more here.
