Tóm tắt

Achieving both a high power factor and low lattice thermal conductivity in thermoelectric (TE) materials has been a longstanding challenge. Herein, we report significant advancements in PbTe-based materials through a band-sharpening approach that incorporates valley modification alongside an innovative core-shell structural strategy. The n-type Ag
