The Role of Layer-Controlled Graphene for Tunable Microwave Heating and Its Applications to the Synthesis of Inorganic Thin Films

In this paper, we present the first method for precisely controlling the heat generated by microwave heating by tuning the number of graphene layers grown by chemical vapor deposition. The conductivity of the graphene increases linearly with the number of graphene layers, indicating that Joule heating plays a primary role in the temperature control of the graphene layer. In this method, we successfully synthesize TiO2 and MoS2 thin films, which do not interact well with microwaves, on a layer-controlled graphene substrate for a very short time (3 min) through microwave heating.
