▎ 摘 要
NOVELTY - Method for growing graphene thin film involves removing metal substrate from high-temperature zone to low-temperature region after closing heating power, rapidly cooling, dissolving carbon in the substrate, freezing, and growing monolayer graphene film with fewer defects. USE - Method for growing graphene thin film by chemical vapor deposition. ADVANTAGE - The method enables growth of graphene thin film with high flatness and quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for growing graphene thin film.
