▎ 摘　　要

NOVELTY - Synthesizing graphene using copper vapor, comprises (a) preparing a substrate, (b) placing copper foil on the substrate, (c) forming copper vapor from copper foil, and (d) contacting graphene precursor gas on the substrate for synthesizing graphene on the substrate. The graphene precursor gas promotes graphene synthesis reaction by the copper vapor. USE - The method is useful for synthesizing graphene using copper vapor (claimed). ADVANTAGE - The method minimizes contamination, and improves quality, and is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene synthesizing element obtained by the above method.
