▎ 摘 要
NOVELTY - Growing single-layer graphene involves (a) fixing copper foil on cathode and placing in acidic electrolyte, applying voltage between working electrode and counter electrode and processing copper foil, (b) placing copper foil sequentially in deionized water and alcohol for cleaning, and blowing copper foil with nitrogen, and (c) placing the copper foil obtained in the step (b) between two layers of graphite sheet, and growing single layer graphene on both sides of the copper foil by chemical vapor deposition. USE - The method for growing single-layer graphene is useful in semiconductor device e.g. integrated circuit device. ADVANTAGE - The method enables to grow single-layer graphene that has high purity.
