【 摘 要 】

Metallic materials attracted much attention in the field of optoelectronics for several applications such as infrared radiation detection. In present study, electronic, optical and thermoelectric spectra of Sm and Ce co doped Bi2Te3 materials have been studied using density functional theory (DFT) calculations. Electronic study of the studied material indicates metallic and good optical and thermoelectric properties. Optical spectra of the doped Bi2Te3 show that absorption lies in visible and near UV region of the radiation. Thus, it seems to have potential applications in optoelectronics. Thermoelectric properties favor the semiconducting nature with high Seebeck coefficient and dominant character of p-type charge carriers.
