Fig. 1. (a) Schematics of CVD synthesis of graphene on PC Cu foil and SC atomic sawtooth Cu substrate. Simple melting-solidification produces SC atomic sawtooth Cu substrate (bottom panel). On the other hand, thermal annealing offers PC Cu foil (upper panel), resulting in growth of SC and PC graphene films, respectively. (b and c) Photographs of as-grown graphene films on (b) PC Cu foil and (c) SC atomic sawtooth Cu substrate.
