Enhanced infrared photoresponse induced by symmetry breaking in a hybrid structure of graphene and plasmonic nanocavities

The infrared photoresponse of a hybrid structure of graphene and plasmonic nanocavities is enhanced by plasmonic symmetry breaking. The hybrid structure overcomes two bottleneck problems of metal-graphene-metal photodetectors, i.e. photoresponse cancellation due to contact symmetry and limited light...
