Abstract
We present a study on the synthesis of Bi₂Te_2.7Se_0.3 powders through an oxide reduction process and also on the effect of the oxide reduction process on the thermoelectric transport properties of the resulting Bi₂Te_2.7Se_0.3 compounds. Starting materials of Bi₂O₃, TeO₂ and SeO₂ were mechanical milled for homogeneous mixing, and then..... More

Abstract
We report the thermoelectric transport properties of n-type Bi₂Te_2.7Se_0.3 compounds prepared by oxide-reduction process. The oxide-reduction process is a recently developed method that can synthesize Bi2Te3-based compounds using only oxide starting materials, which is advantageous in terms of the diversity of the starting materials and cost efficiency. In this study,..... More
