Processes of heterogeneous crystallization of AIIIBV compounds usually differ substantially from homoepitaxial processes. Models describing thermodynamic equilibrium conditions in both three‐ and four‐component homogeneous systems without consideration of the phenomena occurring at the substrate–epilayer interface encounter many limitations. The phase diagrams presented in the literature since long (forming the basis of the selection of technological regimes, in the classical sense), for a wide range of sets require the use of suitable correction of thermodynamic parameters of the systems under consideration. In the present paper a new concept is presented of the physical description of the conditions of thermodynamic quasi‐equilibrium during liquid phase epitaxy of the AxB1–xCyD1–y‐type AIIIBV compounds, assuming pseudomorphic coupling at the substrate–epilayer interface. The relation between the liquidus and solidus curves for the GaxIn1–xPyAs1–y system for its typical heterocomposition is also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
