The problem of the acceptor impurity band formation in the Hg 1− x Cd x Te alloy with ϵ g ≦ 0.3 eV is discussed. Within the coherent potential approximation the density of states as a function of impurity concentration and alloy composition is calculated. The dependence of the impurity band centre location on alloy composition is obtained. The dependence of the acceptor impurity activation energy on the impurity concentration is determined.
