Article Title

Tunable D peak in gated graphene

Keywords

graphene, gating, defects, doping, electro-chemistry

Abstract

We report the gate-modulated Raman spectrum of defective graphene. We show that the intensity of the D peak can be reversibly tuned by applying a gate voltage. This effect is attributed to chemical functionalization of the graphene crystal lattice, generated by an electro-chemical reaction involving the water layer trapped at the interface between silicon and graphene.
