▎ 摘　　要

NOVELTY - Graphene structure 10 comprises substrate 11, and directly grown graphene 20, 21 that is directly grown on a surface of the substrate and has a controlled surface energy. The controlled surface energy of the directly grown graphene has an increased surface energy of the directly grown graphene. USE - Graphene structure used in electronic device. ADVANTAGE - The graphene structure has chemical stability, large surface area, and increased surface energy, and graphene is applied to semiconductor devices. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) Method of forming graphene structure, involves preparing a substrate; directly growing graphene on a surface of the substrate using a plasma enhanced chemical vapor deposition (PECVD) process, and the directly growing graphene including changing a surface energy of a graphene to provide a directly grown graphene having a controlled surface energy. (2) Electronic device comprises the graphene structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of graphene structure.
