Calculation of InAsBi ternary phase diagram

Abstract The phase diagrams of the In As Bi system were predicted at different temperatures by using the Calphad method. The calculations were based on the thermodynamic properties of the constituent binary systems. These properties were collected from selected literature. They were then used to calculate the constituent binary phase diagrams (In As, In Bi and As Bi) and the results were compared with the experimentally determined phase diagrams for evaluating the reliability of the binary data before the ternary phase diagrams were calculated. The isothermal sections at different temperatures and liquidus projection of the In As Bi ternary system were calculated. The calculated results predict the domination of solid phases at low temperatures and show also that the fusion temperature depends on crystallographic structure of InAsBi and the chemical Bi and In concentrations. Such results were helpful for successful growth of InAsBi alloys.
