Optimization of thermoelectric properties of n-type Mn- and Te-doped Mg3Sb2-x Bi x phases
Abstract
This study explores the effects of Mg and Bi amounts, ball milling duration, and sintering conditions on the purity and thermoelectric properties of the Mn- and Te-doped Mg3Sb2-x Bi x phases (Mg2.97+y Mn0.03Bi x Sb1.99-x Te0.01). We found that excess Mg is necessary to achieve phase pure samples, but too much Mg forms impurities that decrease thermoelectric efficiency. Increasing Bi content leads to lower phase stability and decomposition. …
