▎ 摘　　要

NOVELTY - Producing nitrogen-doped graphene comprises coating carbon and nitrogen sources on a surface of copper catalyst or placing carbon and nitrogen sources on a copper catalyst and then continuously introducing into a non-oxidizing gas reactor and reacting the mixture at a temperature of 600-900 degrees C. USE - The method is useful for producing nitrogen-doped graphene, which is useful in the manufacture of optical and/or electrical devices (all claimed) such as FET. ADVANTAGE - The method is capable of simply and economically producing the large area nitrogen-doped graphene with high quality and improved electrical characteristics and light transmittance in an industrial manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the nitrogen-doped graphene prepared by the method.
