摘要：

Thermoelectric and optoelectronic properties of pure and doped Bi2Te3 with Se have been investigated using full potential linearized augmented plane waves (FP-LAPWs). The generalized gradient approximation with spin orbit coupling (GGA + SOC) and the semi-classical Boltzmann transport theory are used. The calculated fundamental band gap of Bi2Te3 is 0.12 eV. The results of Pauli magnetic susceptibility show that the superconductivity transition temperature is about 5 K with different intensities for all compounds. The optical results show that metallic character is observed for energy range 1.60-6.35 eV. The obtained results are impotent for increasing the quality of thermoelectric and optoelectronic properties of materials based on Bi2Te3. (C) 2013 Elsevier B.V. All rights reserved.
