A correlation between graphene domains grown on the outer and the inner surfaces of Cu pockets is found, which discloses a new graphene growth mechanism based on the fast diffusion of carbon atoms through the 25 micrometer‐thick Cu foil, confirmed by isotopic labeling. Subsequently, on the outer surface of the Cu pocket, bilayer graphene with a coverage of about 78% is grown.
