Abstract
In this study, the effect of Sb incorporation on the thermoelectric transport properties of tetradymite-type Pb(Bi_2-xSb_x)Te₄ (0≤x≤1) compounds is presented. PbBi₂Te₄ (x = 0) possesses a high electron concentration of ~1.6×10²⁰/cm³ at room temperature and exhibits n-type degenerate semiconductor behavior, in which electrical conductivity decreases and negative Seebeck coefficient increases.....
