Abstract: New experimental data confirming our suggestion about the universal character of critical phenomena accompanying the transition from "an impurity gas" to "an impurity condensate" with impurity concentration increasing are presented. The existence of the range of anomalous growth in the charge carrier mobility under transition to heavy doping is established for PbTe–PbSe solid solutions. The experimental results are analyzed on the basis of percolation theory taking into account alloy scattering and spatial correlations of impurity centers.
