Abstract
We have used resonant Raman scattering by longitudinal optical (LO) phonons to analyze GaSb/GaAs and InSb/GaAs interfaces for GaSb and InSb grown on (100) GaAs by molecular-beam epitaxy. Striking differences with respect to the abruptness of the interface and the minimum layer thickness required to achieve a good crystalline quality were found. Further, the position of the Fermi level at the surface of epitaxial InSb has been studied by electric-field-induced LO phonon scattering.
