Abstract
Significant progress has been made on searching for good thermoelectric materials with high thermoelctric figure-of-merit (ZT) in the last two decades for improving the energy conversion efficiency from heat to electricity. We found nanostructure approach is especially helpful in increasing the ZT. Recently we have achieved a significant advance in improving the ZTs of half-Heuslers and Zintl materials. These materials may find promissing applications in power generation from heat sources in mid-high temperature range.
