Abstract
Impurity-mediated free-carrier absorption was analyzed theoretically t aking into account the possible spatial impurity correlations. The eff ect of correlations was included via the structure factor S(q) obtaine d from finite temperature Monte Carlo simulations of ordering in the i mpurity system. From the comparison of the experimental data with the results of calculations it is demonstrated that the ordering of charge d centers exists for HgSe:Fe in a wide temperature range.
