▎ 摘 要
NOVELTY - Growing single crystal graphene on a metal substrate comprises placing metal substrate and alkali metal halide in a reactor, inducing chemical vapor deposition of graphene on the metal substrate by heating while injecting a graphene precursor into the reactor. USE - The method is useful for growing single crystal graphene on a metal substrate. ADVANTAGE - The method: realizes high quality with uniform physical properties; produces high-performance graphene in a large area in a short time; and is economical. The graphene has excellent electrical, mechanical, and optical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for single crystal graphene.
