High-Performance n-Type Mg3Sb2-Based Thermoelectrics via Mn Doping and Mg Compensation
The n-type Mg3Sb2-based thermoelectric materials show great potential in waste heat recovery. However, Mg loss during high-temperature processing induces donor-type defects that strengthen ionized impurity scattering (IIS) and force a trade-off between electrical and thermal properties. To overcome this bottleneck, t...
