摘要：
Graphene shows extraordinary optical and electrical properties that can be combined with some metallic micro-nanostructures. We experimentally investigated the electric tuning of Raman scattering in both a monolayer graphene and a monolayer graphene with gold nanorods (AuNRs). It is found when a gate voltage is applied on graphene from −30 to 30 V, the G and 2D peaks of the graphene structures can both be tuned. More importantly, the tuning can be significantly enhanced by the AuNRs on graphene, including the change of the peak position, width and the intensity. Our findings may provide a new way for studying enhanced tunable Raman scattering of graphene structures.
