The results of the studying of thermo- e.m.f., electrical conductivity and thermal conductiv-ity coefficients for PbTe over the temperature range 80—300 K have been presented. It is estab-lished that in non-annealed PbTe samples with the reduction of temperature change in the conduc-tivity from electronic to hole type occurs at low temperatures. After annealing at this sample n-type conductivity is observed over all investigated temperature range.
