Unlocking High-Performance Te-Free p-Type Thermoelectrics via Cu Doping in Entropy-Engineered Cd0.5Zn0.5Sb Zintl.
Zintl phases are crucial for Te-free power generation and electrical cooling modules, which are considered next-generation thermoelectric (TE) technology. While n-type Zintl materials, such as Mg3Sb2, have achieved remarkable performance, their p-type counterparts are restricted by electron-phonon coupling. This work d...
