%X A new type of disorder may occur in artificial superlattices, arising from the randomness in the layer thicknesses. We treat here its effect on the phonon structure. A modification of the infinite order perturbation theory by Wu et aL (1974 a, 1974 b) serves well to give satisfactory solutions of the problem.
