Abstract

Many experiments have shown that, with increasing temperature, the forbidden zone of the semiconductor decreases but there are some accelerated semiconductors (PbTe, PbS, PbSe) where, with increasing temperature, the forbidden zone of the semiconductor increases. In the work, this anomaly is explained by the model of the temperature dependence of the energy states.
