Thermoelectric materials for energy conversion are more and more promising due to the recent breakthroughs in enhancing the dimensionless thermoelectric figure-of-merit(ZT)by nanostructuring approach.I will do a detailed review on the progresses of enhancing the thermoelectric figure-of-merit of a few materials: bismuth tellurides,skutterudites,lead tellurides,lead selenides,half-Heuslers,SiGe alloys,etc.,and followed with a couple of examples of using these materials for applications in waste heat conversion.The main scheme is to enhance the ZT in these materials by studying the compositions and creating nanostructures to reduce the thermal conductivity and simultaneously increase the power factor.
