▎ 摘 要
NOVELTY - A metal layer (2) is contacted with carbon-containing layer (3), heated to dissolve the carbon (5) in carbon-containing layer in the metal layer, and then cooled to deposit the carbon in metal layer as graphene on surface of substrate (1), to obtain graphene substrate. USE - Manufacture of graphene substrate used for semiconductor element (all claimed) for electronics, optoelectronics and spintronics. ADVANTAGE - The graphene substrate is economically manufactured with excellent productivity, mechanical property and chemical property. DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of manufacture of graphene substrate. Substrate (1) Metal layer (2) Carbon-containing layer (3) Carbon (5) Other element (6)
