Raman mappings of a single crystal graphene grain after transfer.
(a) Optical image of the graphene sample on a SiO2/Si substrate. (b–d) Intensity mappings of the D, G and 2D Raman peaks respectively, for a single crystal graphene grain. The spatial and spectral resolutions of the measurements are 1 μm and 1 cm−1 respectively.
