description New ordered compounds derived from semiconductor and metallic alloys for special values of the composition x were studied. The types of ordered compounds were cataloged. A goal was to determine the stability of the new ordered states for both low and high temperatures. The properties of both the new stable and metastable compounds, e.g., band gaps were determined. Finally, the validity of a micro-structure model of metastable alloys was tested. We have determined the structural properties of a number of new ordered compounds using a valence-force-field (VFF) model of strain. Specifically, we have determined such quantities as strain energies, bond lengths, and dimensions of unit cells.
