Inhibiting Mg Diffusion and Evaporation by Forming Mg‐Rich Reservoir at Grain Boundaries Improves the Thermal Stability of N‐Type Mg3Sb2 Thermoelectrics

N‐type Mg3Sb2‐based thermoelectric materials show great promise in power generation due to their mechanical robustness, low cost of Mg, and high figure of merit (ZT) over a wide range of temperatures. However, their poor thermal stability hinders their practical applications. Here, MgB2 is introduce...
