- Abstract
Single crystals of Pb0.75Sn0.25Te with additions of Pb and Sn up to 1.0 at.% were grown, thermoelement legs were created on their basis, and their electrical properties were studied in the range of ~ 77–300 K. It was shown that atoms of additional Pb or Sn at low contents, being located in cation vacancies of crystals, lead to a decrease in the hole concentration, a change in the conductivity type, an increase in the specific resistance ρ and contact resistance rk of the thermoelement legs, and at high contents, creating donor centers in the crystals, they reduce ρ and rk. The specific contact resistance of the legs, as well as their temperature dependences, are also determined by the diffusion of the connecting alloy components into the near-contact region of the crystals. The thermoelectric figure of merit of the studied crystals with a 1.0 at.% Pb additive and the legs of thermoelements based on them reach values of 1.7 × 10–3 K−1 and 1.16 × 10−3K−1, respectively, at ~ 300 K.
