Abstract
Single crystals of Pb0.75Sn0.25Te solid solutions containing up to 1.0 at % excess Pb have been grown by the Bridgman method, and their thermoelectric properties have been studied in the range ~90–300 K before and after heat treatment at 673 and 773 K. The results demonstrate that excess Pb and heat treatment conditions have a significant effect on the electrical conductivity, thermoelectric power, and thermal conductivity of the material and their temperature variation. The highest 300-K thermoelectric figure of merit is offered by the material containing 1.0 at % excess Pb and annealed at 773 K, which is due to its rather high thermoelectric power (~160.1 μV/K) and low lattice thermal conductivity (∼1.04 × 10–2 W/(cm K)).
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
