Abstract

We have shown that (Pb_1-mSn_mTe)_1-x(PbS) _x where m = 0.05 and x = 0.08 exhibits a ZT of ∼1.4 at 700 K. This system incorporates two thermoelectric systems: PbS_xTe _1-x and Pb_1-xSn_xTe. Here we report the thermoelectric properties of PbS_xTe_1-x (x = 0.08 and 0.30). The material Pb5_0.08Te_0.92 exhibits nucleation and growth of PbS precipitates, while PbS_0.30Te_0.70 exhibits PbS precipitation through spinodal decomposition phase separation. We report the thermoelectric properties of this system as a result of the differing precipitation phenomena.
