Photo-modulated optical and electrical properties of graphene

Abstract Photo-modulation is a promising strategy for contactless and ultrafast control of optical electrical properties photoactive materials. Graphene an attractive candidate material photo-modulation due to its extraordinary physical relevance wide range devices, from photodetectors energy converters. In this review, we survey different strategies graphene, including photogating, generation hot carriers, thermo-optical effects. We briefly discuss the role nanophotonic maximize these effects highlight fields application techniques.
