Abstract: The effect of elastic strains produced in epitaxial Zn$_x$Cd$_{1-x}$Te alloy layers during deposition on the CdTe substrate on the parameters of growth is studied experimentally and theoretically. Phase equilibria between the elastically strained alloy layer, the crystal lattice of which is continuously (coherently) matched to the crystal lattice of the bulk substrate, are described by a coherent state diagram. The processes of mass transfer during the formation of heterostructures on the basis of the above-mentioned alloys and the substrate formed of the initial binary compounds are described in the context of the model of diffusion-limited crystallization. It is shown that such thermodynamic concepts can be used to describe experimental data on the parameters of the process of crystallization of elastically strained alloy layers during the formation of heterojunctions in the system involving the Zn–Cd–Te alloy and the substrate based on the initial binary compound.
