Abstract
The reasons for anomalous growth in the thermopower of metal borides at high temperatures is analyzed. It is shown that this behavior of thermopower cannot be explained within the present models of charge transfer in disordered semiconductors. The anomalous growth of thermopower in polar materials can be interpreted by taking into account the temperature dependence of the elastic coupling constant or of the polarizability.
