Abstract
A method for synthesizing a multilayer graphene is provided. Specifically, the multilayer graphene can be produced by performing a step of forming a catalytic metal layer on a substrate, a step of heat-treating the catalytic metal layer on the substrate while supplying methane gas, and a step of synthesizing a multilayer graphene on the heat-treated catalytic metal layer. As described above, the multilayer graphene having a large area can be grown directly on a substrate, by heat-treating the catalytic metal layer using methane gas, prior to the step of synthesis of graphene. In addition, as the the number of layer of the multilayer graphene can be controlled by changing the synthesis time of the multilayer graphene, the multilayer graphene with the desired number of layers can be easily produced.
