▎ 摘　　要

NOVELTY - Producing graphene comprises forming graphene on a non-metallic surface of a substrate by chemical vapor deposition in a chemical vapor deposition reaction chamber and adding a precursor in a gas phase and/or suspended in a gas into the reaction chamber. The precursor comprises 4-10C branched organic compound including three methyl groups, and carbon, hydrogen; and oxygen, fluorine, chlorine and/or bromine are optionally substituted. USE - The graphene is useful for electronic devices. ADVANTAGE - The graphene has improved electronic properties which is directly formed on non-metallic surfaces of substrates and excellent sensitivity of devices.
