Temperature effect on spatial correlations of impurity ions in HgSe: Fe crystals

The spatial correlations in the arrangement of iron ions in HgSe: Fe compounds are described by the pair correlation function calculated within the hard sphere model. The temperature effect is taken into account by substituting the thermodynamic mean for the correlation sphere radius. The thermodynamic averaging is performed using the Einstein approach. The temperature dependences of the mobility of electrons scattered by a spatially correlated distribution of iron ions are calculated, and the results of these calculations are compared with the experimental data.
