Abstract
This paper reports on the study of the effect of interband scattering on the thermoelectric figure-of-merit of semiconductors and semimetals. It has been shown that the inclusion of interband scattering in the case of two types of carriers of the same sign leads to a decrease in the thermoelectric figure-of-merit. By contrast, if the material contains carriers of two types of opposite signs and the conduction and valence bands overlap, as is the case with semimetals, the interband scattering favorably affects on the magnitude of the thermoelectric figure-of-merit.
