Figure 2From: Van der Waals epitaxy and characterization of hexagonal boron nitride nanosheets on grapheneSEM images of graphene and h-BN/graphene on SiO 2 /Si. (a) Multilayer graphene on SiO2/Si before CVD, with the graphene boundary, and wrinkling, indicated by arrows. (b) h-BN nanosheets on a narrow graphene belt on SiO2/Si, with the graphene boundary indicated by arrows. (c) h-BN nanosheets on a larger graphene film, with wrinkles indicated by arrows.Back to article page
