## Abstract The vibrational properties of the mixed crystals Ga~1β€”__x__~In~__x__~As and Ga~1β€”__x__~In~__x__~Sb are investigated using the coherent‐potential approximation (CPA). These IIIβ€”V systems switch from one‐mode to two‐mode behaviour as the composition is changed. Results are obtained for a
