摘要：In the present study, the temperature dependences of the thermoelectromotive force (thermo–emf) in copper selenide, substituted in a small concentration, were studied. The results of the measurements showed that the thermo–emf coefficient of the samples increases, and the conductivity decreases with increasing silver concentration in its composition. These results allow – with optimal selection of the doping regime and protective coatings – to develop on the basis of nanostructured copper selenide an effective thermoelectric for use at temperatures of 20–500°C as p–type semiconductors suitable for increasing the efficiency of thermoelectric generators.
