Electronic structure and thermoelectric properties of Bi-2(Te1-xSex)(3) compound
Artikel i vetenskaplig tidskrift, 2013

A first-principles study has been performed to evaluate the electronic structure and thermoelectric properties of Bi-2(Te1-xSex)(3) compound. The transport coefficients are then calculated within the semiclassical Boltzmann theory, and further evaluated as a function of chemical potential assuming a constant relaxation time and an averaged thermal conductivity. Our theoretical calculations show that the ZT value is 1.43 for Bi-2(Te1-xSex)(3) system, and it agrees well with previous experimental data.
