| Abstract |
Thermoelectric (TE) materials can directly convert heat into electricity and vice versa through the Seebeck and Peltier effects. TE materials provide a solid-state solution for harvesting waste heat from industrial processes, automotive exhausts, and even human bodies. In this study, SnO2 coating on p-type Bi-Sb-Te alloy was performed to suppress the bipolar effect and improve TE performance. |
