▎ 摘　　要

NOVELTY - Manufacture of graphene (10) involves forming graphene into film on magnesium oxide (111). USE - Manufacture of graphene (claimed). ADVANTAGE - The method economically provides graphene having high mobility and film quality, with reduced impurities. The graphene is directly formed on a transparent insulator board. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of structure of graphene. Graphene (10) Magnesium oxide single-crystal thin film (11) Nickel oxide buffer layer (12) Yttria-stabilized zirconia monocrystal substrate (13) Bulk single crystal (14)
