报告摘要：
The widespread use of thermoelectric generators has been limited by the low material efficiency of the thermoelectric material. A number of strategies for Complex Thermoelectric Materials [1] with higher Thermoelectric figure of merit, zT, are being actively studied. Complex electronic band structures provide mechanisms to achieve high zT in thermoelectric materials through band structure engineering. High zT is obtained p-type PbTe and PbSe which contains both light and heavy valence bands that can be engineered by alloying to achieve high valley degeneracy which leads to an extraordinary peak zT of about 2 at 750K [2].
