Discovery of high-performance low-cost n-type Mg3Sb2-based thermoelectric materials with multi-valley conduction bands
Zintl-phase thermoelectrics are predominantly p-type. Here, Zhanget al. use tellurium to n-dope Mg3Sb1.5Bi0.5and obtain thermoelectric figures of merit up to 1.6 at 700 K. Calculations show that these performances result from a conduction band with sixfold valley degeneracy.
