What is it about?
The approach taken in this paper in order to modify the scattering features of electrons and phonons and improve the figure of merit of thermoelectric PbTe is to alter the microstructure at constant chemistry. A lamellar pattern of PbTe/GeTe at the nano- and microscale was produced in Pb0.36Ge0.64Te alloy by the diffusional decomposition of a supersaturated solid solution. The mechanism of nanostructuration is most likely a discontinuous spinodal decomposition.
