Based on the ideas about the uniqueness of carbon nanostructures, the electron-phonon interaction is considered. A thermoelectric model based on the mechanism of the ballistic phonons electron drag is presented. The experiment with a thermoelectric generator based on film carbon nanostructures is analyzed.
A thermal conductivity model based on the mechanism of heat transfer through the boundary of the graphite-like/diamond-like regions is presented. A thermoelectric generator based on a composite: a graphite-like matrix with inclusions of diamond nanoparticles, is proposed. Both considered mechanisms operate in it and record values of the thermoelectric generator parameter can be achieved.
The graphene thermoelectric coefficient was calculated and a model of a thermoelectric generator based on a composite: a graphite-like matrix with graphene inclusions was proposed.
