▎ 摘　　要

NOVELTY - Doped graphene is prepared by converting polycrystalline metal catalyst thin film into single crystal metal catalyst thin film through abnormal grain growth method and synthesizing doped graphene on single crystal metal catalyst thin film by chemical vapor deposition. USE - Preparation of doped graphene (claimed). ADVANTAGE - The doped graphene production method is capable of controlling a dopant distribution pattern of doped graphene by controlling a crystal grain distribution pattern of a catalyst metal.
