SOLID-SOLUTION INXGA1-XASYSBZP1-Y-Z - A NEW MATERIAL FOR INFRARED OPTOELECTRONICS .1. THERMODYNAMIC ANALYSIS OF THE CONDITIONS FOR OBTAINING SOLID-SOLUTIONS, ISOPERIODIC TO INAS AND GASB SUBSTRATES, BY LIQUID-PHASE EPITAXY

The diagrams of melt-solid solution (fusibility curves) and solid solu tion (I)-solid solution (II) (surfaces of spinodal decomposition of so lid solutions) phase equilibria in the five-component system In-Ga-As- Sb-P (the solid solutions are isoperiodic to the GaSb and InAs substra tes) are calculated. The concentration ranges of the isovalent substit ution solid solutions InxGa1-xAsySbzP1-y-z, which are accessible for s ynthesis by liquid-phase epitaxy, are calculated.
