Abstract AITranslate

The interface has a significant regulatory effect on the electroacoustic transport properties of the material.Therefore,the effect of homogeneous interface density on thermoelectric performance of P-type Bi0.5 Sb1.5Te3 alloy was investigated. The results show that the electrical conductivity of the alloy decreases and Seebeck coefficient increases with the increase of homogeneous interface density. Meanwhile,the ther mal conductivity decreases attributed to the enhanced scattering of phonons by increasing homogeneous in terface density. Because the sintered sample prepared by pulverizing for 1 min has the optimal electrical properties,it has excellent thermoelectric performance in the high temperature range.
