Phase equilibria in the InP-InAs-InSb quasi-ternary system

G M − x curves were calculated in order to plot a solubility surface for the InP-InAs-InSb quasi-ternary. A two-phase field (a mixture of InAs t− x Sb x solid solution (ss) and InP x As 1− x ss) decreases with increasing temperature, though occupying a considerable part of the concentration triangle...

Description
Summary:G M − x curves were calculated in order to plot a solubility surface for the InP-InAs-InSb quasi-ternary. A two-phase field (a mixture of InAs t− x Sb x solid solution (ss) and InP x As 1− x ss) decreases with increasing temperature, though occupying a considerable part of the concentration triangle even at moderate subsolidus temperatures. An experimental X-ray power diffraction study of alloys with compositions lying along the InP 0.8 As 0.2 -InsB polytherm verified that the InP x As y Sb 1− x − y ss at room temperature is stable when the InAs percentage in alloys exceeds 65 mol %. Liquidus surface isotherms of the InP-InAs-InSb quasi-ternary were plotted using the regular solutions model.
