Abstract
The n-type $Bi_2(Te,Se)_3$ powders were fabricated by melting/grinding method and were hot-pressed in order to compare thermoelectric properties of the hot-pressed specimens with those of the $Bi_2(Te,Se)_3$ ingot. Effects of mechanical milling treatment of the $Bi_2(Te,Se)_3$ powders on thermoelectric characteristics of a hot-pressed specimen were also examined. The hot-pressed $Bi_2(Te,Se)_3$ exhibited power factors of $27.3{\sim}32.3{\times}10^{-4}W/m-K^2$ which were superior to $24.2{\times}10^{-4}W/m-K^2$ of the ingot. The $Bi_2(Te,Se)_3$, hot-pressed after mechanical milling treatment of the powders, possessed a non-dimensional figure-of-merit of 1.02 at $100^{\circ}C$ and exhibited extrinsic-intrinsic transition at $130^{\circ}C$.
