Properties of as-synthesized graphene. (a) Typical HRTEM image of an as-synthesized graphene, indicating the formation of monolayer graphene. Inset: selected area electron diffraction pattern of the graphene. (b) Raman spectrum of an as-synthesized graphene on a Si/300-nm SiO2 substrate. (c) The transparency spectrum of the graphene on a quartz substrate.
