Description
The thermoelectric effect in epitaxial graphene formed on the surface of a size-quantized a metallic film is considered in the context of the Davydov model. The approach based on the Kubo formula for conductivity and thermoelectric coefficient is used. It is shown that near the energy levels of size quantization, the thermopower of epitaxial graphene increases to a giant value of 200 μV·K-1, which is almost seven times higher than the thermoelectric power of isolated graphene (about 30 μV·K-1)
