▎ 摘　　要

NOVELTY - Producing graphene comprises doping a carbon in a metallic board, fusing the metallic board with carbon by irradiation to form a carbon-doped metallic board, cooling the fused metallic board, where the doped carbon moves to a metal board surface after the cooling process and finally growing grapheme on the metal board surface. USE - The method is useful for manufacturing graphene (claimed). ADVANTAGE - The graphene can be grown progressively in a desired domain. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene (104) formed on a doped metallic board by irradiating torch in a cooled mode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene. Non-metal substrate (101) Metal layer (102) Graphene asterisk (104)
