Abstract. Within the diffusion-limited growth model, the kinetic analysis of the LPE
process for Te Hg Cd x 1 x − solid solutions is carried out. It is assumed that a phase
equilibrium exists on the interface, and the concentrations of components are connected
by the equations of phase equilibria in the frame of the model of polyassociated
solutions. These equations serve as the boundary conditions in solving the diffusion mass
transfer problem. The developed thermodynamic model of growth allowed us to achieve
the precision description of solid solutions, in particular to predict the regimes of the
growth of layers with a given composition in the Cd-Hg-Te system.
Keywords: LPE, growth kinetics, semiconductor solid solutions.
