Abstract

The usefulness of consistent phase diagram and thermodynamic data as a powerful tool for the development of improved contact materials to compound semiconductors like GaAs is demonstrated. Predictive calculations of ternary Ga-As-M phase diagrams in the solid state using simplifications have been performed as a basis for future work. A simple scheme for representation of thermodynamic driving forces of possible reactions between the various phases is given. The phase diagrams are classified into four different possible types and examples are given for the three types which presumably exist for the metals studied.
