Tóm tắt

In the preparation process of p-type BiSbTe alloys, conventional powder metallurgy techniques often use excess Te to optimize the performance. Large-scale industrial zone melting also attempts to compensate for Te during raw material preparation. However, it is unclear whether the thermoelectric performance of p-type BiSbTe improves with excess Te in industrial production as well as the thermal stability of the material and devices. This study focuses on p-type zone-melted BiSbTe materials with different doping and solid solution contents. The results show that 3 wt % Te doping increases the maximum
