摘要：

We report on a Raman study of lattice vibrations in the diluted magnetic semiconductors Zn1-xFexSe (0 < x < 0.64) and Zn1-xCoxSe (0 < x < 0.10). Both alloys possess a homogeneous crystal phase having the zinc-blende structure. The observed dependence of the first-order optical-phonon spectrum of x follows the mixed-mode behavior and is well described by the modified random-element isodisplacement model. Several physical parameters for the end members, cubic FeSe and CoSe, ard deduced from the fits to the composition dependence of the lattice vibrations.
