Abstract

In this work a part of the state diagram of PbSe-TbSe system on the PbSe side has been constructed. Solid solutions based on lead monoselenide in the region of 0-8 mol% have been obtained in the system. Some electrophysical properties (thermo-e.d.s., electrical conductivity and thermal conductivity) of the obtained alloys at the temperature range of 300-700 K were investigated and the thermoelectric goodness of fit (Z, ZT), efficiency d and power factor P were determined. The occurrence of high thermoelectric efficiency in the samples of composition Tb0,05Pb0,95Se was found.

Keywords: Solid Solutions, Electrical Conductivity, Power Factor, Thermo-E.D.S., Thermal Conductivity, Thermoelectric Goodness, Efficiency.
