Material on the basis of PbTe for p - branches of thermoelectric coolers

摘要

The results of the studying of thermo-e.m.f. (α), electrical conductivity (σ) and thermal conductivity (χ) coefficients for PbTe over the temperature range 80/300 K have been presented. It is established that in non-annealed PbTe samples with the reduction of temperature change in the conductivity from electronic to hole type occurs at low temperatures. After annealing at this sample n-type conductivity is observed over all investigated temperature range.
