Influence of different modulus on the thermoelectric performance of materials

Abstract

Abstract: Based on Boltzmann transport equation and Landauer equation, the characteristics of the thermoelectric parameters such as the figure of merit, electrical conductance and power factor for two kinds of modulus are studied in this paper, including a constant and a Gauss-typed distribution functions with a finite energy spectrum width. Compared with Delta-typed modulus, it is found that the figure of merit will be decreased but the electrical conductance and the power factor will be increased after the spectrum width is introduced. The thermoelectric performance of the two kinds of modulus would be more practically meaningful than that of the Delta-typed modulus.

Key words: material, nanomaterial, modulus, thermoelectric performance, ballistic transport
