NOVELTY - A graphene manufacturing method includes: selecting a substrate; sputtering or depositing at least a mixed layer, which is constructed of a carbon material mixed with metal material, on the top of the substrate; subjecting the said substrate and mixed layer to an annealing treatment; after the annealing treatment, the metal material in the mixed layer will be deposited downwardly to form a metallic layer, while the carbon material in the mixed layer will precipitate to form a grapheme layer. Alternatively, the method includes: selecting a substrate; sputtering or depositing at least a carbon material layer on top of the substrate; subjecting the said substrate and carbon material layer to an annealing treatment; after the annealing treatment, the carbon material layer will precipitate to form a grapheme layer. By the above manufacturing method, high quality and large-area of continuous graphene layer can be directly generated on the metal substrate or nonmetal substrate.
