LAWS OF PHASE TRANSFORMATIONS OF A*993B*995 MULTICOMPONENT SYSTEMS UNDER CONDITIONS OF THE LIQUID HETEROEPITAXY

A*993B*995 solid solutions, A*993B*995 heterostructures, phase boundaries, heteroepitaxy from the liquid phase, optical properties of A*993B*995 are considered in the paper aiming at the investigation and generalization of physical-chemical laws of the semiconducting heterostructure formation on the base of A*993B*995 multicomponent systems from the liquid phase. The development of mathematical models for the calculation of structure parameters and technological regimes of their obtaining is also the aim of the paper. As a result the mathematical description of heteroepitaxy of semiconducting solid solutions has been given as well as the thermodynamic description of the "multicomponent liquid - elastic-stressed solid phase" metastable equilibrium. The crystallization trajectory is in limits of a phase space and is modifying on polyhedration laws. The modulation character of crystallization has been determined as well as relaxation mechanisms of epitaxy. The compensation isovalence alloying has been held. Boundaries of phase regions in A*993B*995 quarter systems have been determined. The program complex for the epitaxial process control of the whole class of A*993B*995 solid solutions has been developed. Relaxation methods for the heterostructure property control have been represented as well as light diodes in 3,8-4,9 mu range, injection lasers with the distributed feedbackAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
