METHOD FOR SYNTHESIZING GRAPHENE USING COPPER VAPOR AND DEVICE COMPRISING GRAPHENE SYNTHESIZED THEREBY

摘要

A method of graphene synthesis using copper vapor is provided. Specifically, a substrate is prepared, a copper foil is placed on the substrate so as to be spaced apart from the substrate, copper (Cu) vapor is formed from the copper foil, There is provided a graphene synthesis method using copper vapor in which the graphene precursor gas is contacted with the copper precursor gas to accelerate the graphene synthesis reaction by the copper (Cu) vapor and graphene is synthesized on the substrate. By not having a separate transfer process, it is possible to synthesize high-quality single-layer graphene (SLG) with minimized damage and contamination of the graphene, have. In addition, the present invention can be applied to various dielectric substrates, and the range of application of the manufactured devices can be expanded.
