Abstract
A new model is proposed to understand multiphonon Raman spectrum (MRS) of II-VI semiconductors. A quasibound state of exciton—LO-phonon complex (EPQBS) in the intermediate state is shown to be responsible for the observed overtone series. The observation of MRS is a natural consequence of our model in which the EPQBS lies in the absorption continum.Keywords
