METHOD FOR USING CARBON SOURCE HAVING MULTIPLE BENZENE RINGS TO GROW GRAPHENE OVER LARGE AREA BY CHEMICAL VAPOR DEPOSITION AT LOW TEMPERATURE

摘要

Disclosed is a preparation method for using a carbon source having multiple benzene rings to grow graphene over a large area by chemical vapor deposition at a low temperature. The method comprises: using an aromatic hydrocarbon having multiple benzene rings as a carbon source, growing graphene on the surface of a copper foil by a carbon source decomposition process or a carbon source spin-coating process; and the aromatic hydrocarbon having multiple benzene rings being benzene or a fused-ring aromatic hydrocarbon.
