- Raman spectroscopy and spectroscopic ellipsometry have been used to characterize Si/Si$\text{}_{0.78}$Ge$\text{}_{0.22}$ superlattices grown by molecular beam epitaxy on (001)Si at different substrate temperatures. The results are interpreted to give information on material and interface quality, layer thicknesses, and state of strain. The observed frequencies of zone-folded longitudinal acoustic phonons in a high quality sample agree well with those calculated using Rytov's theory of acoustic vibrations in layered media.
