Discovery of high-performance low-cost n-type Mg₃Sb₂-based thermoelectric materials with multi-valley conduction bands.

Energy gaps of Mg 3 Sb 2− x Bi x show a decreasing trend from 0.43 to 0.08 eV as x increases from 0.5 to 1.5 ( Fig. 3b ), suggesting that the bipolar effect will be obvious when x >1.
