We investigate the thermoelectric power coefficient, electrical conduc
tivity, and thermal conductivity of PbSe doped with chlorine and sodiu
m in the temperature interval 300-950 K. The values of the kinetic coe
fficients and thermoelectric figure of merit are compared with analogo
us data for PbTe. An improvement in the thermoelectric parameters of p
-PbSe is observed at high temperatures after additional isovalent dopi
ng by cadmium and manganese impurities. (C) 1996 American Institute of
