▎ 摘　　要

NOVELTY - Graphene structure comprises a substrate, graphene on a surface of the substrate, and a bonding region, where a material of the substrate (110) and carbon of the graphene are covalently bonded, between the surface of the substrate and the graphene, where the bonding region (120) has a 40-60 wt.% silicon carbide. USE - Graphene structure for use in a semiconductor device. ADVANTAGE - The graphene has high electric mobility and excellent thermal characteristics compared to silicon, chemical stability and wide surface area, improves adhesion between graphene and a substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the metal layer deposited on a top surface of a graphene layer. 110Substrate 120Bonding region 130Graphene layer 140Metal layer
