Abstract

The current chapter reviews the principles and methods for exploiting thermodynamically driven phase separation effects such as nucleation and growth and spinodal decomposition for enhancing the thermoelectric figure of merit through bulk nanostructuring of selected IV-VI systems. Special emphasis is laid on the p-type (GeTe)0.87(PbTe)0.13 and the n-type (Pb0.95Sn0.05Te)0.92(PbS)0.08, exhibiting very high maximal ZTs of 2.2 and 1.5, respectively.
