Resonant Exciton-Phonon Spectra in ZnCdSe/ZnSe Single QW: Raman Scattering and Hot Luminescence; Extended and Localized Excitons

Abstract

The presented paper investigated in detail the structure and intensity of resonant exciton-phonon (REP) spectra in ZnCdSe/ZnSe QW structures as functions of tunable laser energy at 8 K. We have found that in REP spectra two types of lines are presented simultaneously. The most intensive REP component correspond to Raman scattering through extended exciton states. Other less intensive REP components correspond to hot luminescence of localized excitons. Analysis of phonon modes which can be involved in formation of REP spectra in our strain QW structures has been carried out.
