Paper Abstract

Optical transitions in the range I .9—4.3eV have been observed in Si:Ge superlattices by spectroscopic ellipsometry (SE) and electron—beam electroreflectance (EBER). Interference is shown to play an important role in both techniques, leading to complications in • interpretation. Strong features may be produced both by multiple reflections from capping layers and from buried growth imperfections.
