N2 - The synthesis and properties characterization of several PbS 1-xjTex x = 0-0.16 samples are presented. Notably it is shown how a local minimum occurs in the thermal diffusivity for the PbS 1-xTex samples at x ∼ 0.03. The thermoelectric properties of doped PbS1-xTex with x = 0.03 are reported and the properties are compared to the pure PbS and PbTe end members. The electronic contribution to the total thermal conductivity is analyzed for PbS1-xTex x = 0.03 and it is shown how the lattice thermal conductivity is significantly lowered compared to single crystalline PbS.
