The carbon's solubility into copper is extremely very low and as a consequence mainly surface diffusion and nucleation of carbon atoms are associated. Due to this along with the growth kinetics, the graphene thickness is limited to predominantly a monolayer. The large advantage would be that the graphene might be https://www.quora.com/profile/Trevor-Flatcher-2/Advantages-of-Silicon-Carbide-Materials-in-High-Temperature-Electronic-Devices-Silicon-carbide-SiC-has-emerged-as-a-c
