▎ 摘　　要

NOVELTY - Production of layered structure (10) involves providing (i) a substrate (1) comprising a top surface (1a) containing a non-electroconductive material, depositing (ii) a catalyst structure onto the top surface, depositing (iii) a graphene structure (3) onto the catalyst structure, and partially removing (iv) catalyst structure located between the substrate and the graphene structure. USE - Production of layered structure (claimed). ADVANTAGE - The method enables economical production of high-quality layered structure having excellent electrical characteristics and mechanical characteristics, high charge carrier mobility, and suppressed generation of defect such as crack and imperfection at edges. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the production of layered structure. Substrate (1) Top surface of substrate (1a) Graphene structure (3) Electroconductive region (4) Layered structure (10)
