摘要：
The investigation results of temperature dependences of thermoelectric parameters in the 140-440 K temperature range are reported for Pb0.78Sn0.22Te < Ge(0.5 at.%)> solid solution, having p-type conductivity. The aim is to determine its perspectives as a promising material for thermoelements. Investigations have shown that the temperature dependences of thermoelectric parameters have some interesting features caused by phase transition observed at temperature 290 K. (C) 2007 Elsevier B.V.
