Figure 3From: Van der Waals epitaxy and characterization of hexagonal boron nitride nanosheets on grapheneRaman spectra. (a) Raman spectra of graphene before CVD (lower plot) and h-BN/graphene after CVD (upper plot). G peaks fitting with Lorentz curves (solid lines) for graphene substrate (b) and h-BN/graphene (c) are shown with their FWHMs, respectively.Back to article page
