| Summary: | <blockquote><blockquote>The paper presents the results of research of X-ray diffraction and thermoelectric parameters (thermoelectric coefficient α, electrical conductivity σ and thermal conductivity coefficient k) of materials based on Lead Telluride: PbTe, PbTe:Sb, PbTe-Sb2Te3, Pb18Ag1Sb1Te20, Pb18Ag2Te20 and PbTe-Ag2Te. Established that the highest values of thermoelectric figure of merit have samples of PbTe:Sb (0,3 at.%) and system Pb18Ag1Sb1Te20, Pb18Ag2Te20. For PbTe:Sb is due to a significant increase of the electrical conductivity. For the other two materials is due to a increase the thermoelectric coefficient and a significant decrease of thermal conductivity compared to pure PbTe. <br /><strong>Keywords: </strong>Lead telluride, doping, solid solutions, LAST, thermoelectric properties.</blockquote></blockquote> |
