Induced defects in sintered lead telluride

Synthesis and Characterization of p-Type Pb0.5Sn0.5Te Thermoelectric Power Generation Elements by Mechanical Alloying

“…Presumably, these changes reflect thermally activated relaxation of metastable transport properties introduced by the nonequilibrium MA processing. 30,31 The small uncertainties in p and l in Table I are the standard deviations resulting from measuring three samples prepared using the same process. These small standard deviations indicate that the process results in reproducible electronic transport properties despite the use of 99.9% instead of ‡99.999% pure starting materials.…”

Solid solution Pb1−xEuxTe: constitution and thermoelectric behavior

“…14 These studies are mainly based on single crystals grown by the Bridgman technique, and only a few studies have reported on the electrical and thermal transport properties of polycrystalline binary PbTe. [15][16][17] Some controversies still exist concerning the basic understanding of the origin of the low lattice-thermal conductivity of lead telluride. [18][19][20] To enhance the thermoelectric performance of PbTe, a series of studies utilizing electron and phonon engineering approaches were performed on chemically substituted materials.…”

Low Temperature Synthesis as a Route for Highly Thermoelectric Efficient Na‐Doped PbTe

“…Interestingly, a smaller ZT of 1.1 at 720 K was reported for Na‐doped PbTe ingots, and nanoscale Na‐rich precipitates were found in PbTe matrix . Overall, the thermoelectric properties of PbTe‐based materials are sensitive to the processing conditions while the synthesis from melt at temperatures higher than 1000 °C is the most common reported in the literature. On the other hand, suggestions to prepare PbTe at much lower temperatures have been previously reported .…”
