Abstract

Raman scattering from a (CdSe)m(ZnSe)n-ZnSe strained quantum well structure, composed of (CdSe)m(ZnSe)n as well layers and thick ZnSe as barrier layers, is presented in this report. Two kinds of ZnSe-like LO phonon confined modes were observed by Raman scattering at 10-300 K. Resonance Raman scattering was accomplished by changing sample temperature and incident photon energy and as a results, up to 7 orders of ZnSe-like LO multi-phonon modes were observed. In the discussion, we suggest that anti-Stokes Raman scattering measurements can provide a meaningful way to distinguish the multi-phonon Raman scattering from hot luminescence.
