Peña Sierra Física, Astronomía y Matemáticas In Ga Sb As LPE The y y x x D C B A − − 1 1 alloys are the conventional materials of the semiconductor heterostructures for the optoelectronicsdevice applications. The liquid phase epitaxy is one of the methods for preparation of the y y x x D C B A − − 1 1 -basedheterostructures. The liquid phase epitaxial processes are fulfilled near thermodynamic equilibrium. Therefore,information on the phase diagram and miscibility gap is necessary for the liquid phase epitaxy growth of they y x x D C B A − − 1 1 alloys. The phase equilibria in the heterogeneous systems with the y y x x D C B A − − 1 1 alloy in theregular solution model are presented. The heterogeneous equilibria are considered as minimum condition of theHelmholtz free energy of the system that is presented as a canonical ensemble. The strictly regular approximation is usedfor description of all phases. The interactions between the nearest and next nearest atoms as well as the oscillationmovement of the atoms are taken into account. The supposition on random distribution of the cations and anions in theirsublattices is used for the configurational entropy. The numerical estimations are fulfilled for the phase diagramconsisting of the ( ) As Sb Ga In , , , liquid solution and the y y x x As Sb Ga In − − 1 1 alloy lattice matched with theGaSb substrate. The obtained theoretical estimations are in good agreement with the available experimental results 2003 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94216402 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
