Multiphonon Raman scattering resonant with two kinds of excitons in a (CdTe${)}_2$(ZnTe${)}_4$/ZnTe short-period-superlattice multiple quantum well

A study of the multiphonon resonant Raman scattering in a (CdTe${)}_2$(ZnTe${)}_4$/ZnTe short-period-supperlattice multiple quantum well (SSQW) has been performed. Overtones up to the 13th order for the ZnTe longitudinal-optical (LO) phonons were observed and identified as due to Raman scattering. The Raman scattering was involved in the ZnTe LO phonons confined in the barriers of SSQW and in short-period superlattices resonant with two kinds of excitons in the barriers and wells of the SSQW, respectively. This may account for up to 13th orders of multiphonon scattering being observed.
