| Abstract: | Thermodynamic and phase diagram data are used to optimize the thermodynamic model parameter values of the liquid phases in four III-V binary systems: In-P, Ga-As, In-As and Al-Sb. An associated solution model is used to describe the thermodynamic properties of the liquid phases and the III-V compound semiconductors are taken to be stoichiometric (or line) compounds. For each of the binary systems, a set of thermodynamic parameters for the liquid and compound semiconductors are obtained. Using these values, the calculated phase diagrams are in agreement with the experimentally determined ones. Moreover, the model-calculated thermodynamic values also in agreement with the experimentally determined values. |
