The recently discovered order-disorder transformations in pseudobinary semiconductor alloys A/sub x/B/sub 1-//sub x/C are shown to belong to a broader class of such transformations in A/sub n/B/sub 4-//sub n/C/sub 4/ semiconducting compounds (e.g., chalcopyrites, for n = 2). Strain energy, set up by the atomic size mismatch between the A--C and B--C bonds, is shown to control the nature of the state of order in chalcopyrites and pseudobinary alloys alike. These considerations lead to a classification of all bulk tetrahedral semiconductors into four classes of order-disorder characteristics.
