Abstract

Resonant Raman scattering at the E₀ gap from longitudinal optical phonons in CdTe/(Cd,Mn)Te multiple quantum wells has been studied near the strain split n=1 exciton ground state. A large resonance enhancement is observed with distinct incoming and outgoing channels, in agreement with luminescence excitation spectra. Phonons are observed from CdTe wells and (Cd,Mn)Te barriers, indicative of small valence-band offsets for this superlattice system. At extreme resonance, striking linewidth broadening and damping effects for the alloy phonon modes are witnessed.
