Abstract

In this work, the doping of n-layer graphenes with C₆₀ is investigated via Raman spectroscopy. The results indicate that C₆₀ can induce hole doping in graphenes, and that the doping level is closely related to the layer number of the graphenes. Moreover, the level of doping in the hybrid of C₆₀ on graphene (C₆₀/G) is more significant than that in the hybrid of graphene on C₆₀ (G/C₆₀).
