Growth of Ga In As Sb solid solutions from the 1yx x y 1yy five-component Ga–In–As–Sb–Pb melt by liquid phase epitaxy

Gallium antimonide GaSb.and its solid solutions are widely used in optoelectronic devices for the ecologically important spectral range 2–5 mm. In this paper we discuss a novel approach of using neutral solvents such as Pb.in GaInAsSb growth process. We employed the excess thermodynamic functions and linear combinations of chemical potentials EFLCP.thermodynamic model to calculate the melt–solid phase diagrams in the Ga–In–As–Sb–Pb system. q1999 Elsevier Science B.V.
