Description
The vibrational properties of Zn/sub x/Cd/sub 1-x/Se phonons are studied using Raman scattering. The change of the LO-phonon spectrum versus crystal composition is found to be of the one-mode type. The TO-phonon behaviour is much more complicated. It exhibits rather anomalous features in the line shape and TO-mode frequency versus crystal composition as well as temperature. The above phenomena are interpreted in terms of the anharmonic coupling between TO-mode and two-phonon states. This coupling is well described by the theory developed. (author)
