Abstract

Homogeneous and graded PbTe samples doped with PbI2 were prepared using powder metallurgical techniques. The samples were examined by SEM, EDS, XRD, and their transport properties were determined. The preparation procedures were optimized with respect to powder particle size, compaction pressure, and sintering parameters. Dopant concentration profiles for optimal power factor in the 50 to 500°C temperature range were calculated on the basis of the experimentally determined transport measurements results.
