Cu<sub>3</sub>SbSe<sub>3</sub>-Alloying-Induced High Thermoelectric Performance and Mechanical Robustness in Bi<sub>2</sub>Te<sub>3</sub>-Based Thermoelectric Materials.
Ontology highlight
ABSTRACT: Bi2Te3-based thermoelectric materials remain the only commercially viable candidates for low-grade waste heat recovery. However, their moderate thermoelectric performance and limited mechanical robustness constrain broader industrial applications. Here, a synergistic enhancement of both the thermoelectric and mechanical properties of Bi0.4Sb1.6Te3.01 is demonstrated by alloying with Cu3SbSe3 via high‑energy ball milling followed by hot pressing. This approach optimizes carrier concentration and reduces microscale porosity, yielding a significant improvement in the power factor across the entire temperature range. Simultaneously, the introduction of stacking faults and dislocations intensifies phonon scattering, ef
