Abstract

Raman and resonant Raman scattering measurements have been performed on two HgTe/CdTe superlattices (SL). HgTe-like and CdTe-like phonon modes were observed, corresponding to layers of Hgl-xCdxTe (x ~ 0.85) rather than of pure CdTe, because of Hg added during the growth process. Pure HgTe phonon modes were also seen. Pure CdTe phonon lines are observed from a HgTe-CdTe SL with a 300 Å CdTe cap. The multiple CdTe phonon outgoing resonances with the E0 + Δ0 gap are studied for this SL and CdTe substrates. An unexplained Raman feature is observed near 430 cm-1.
