Flow Modulation Epitaxial growth of short period GaInAs/InP superlattices was investigated. Superlattice quality was assessed by Double Crystal X-Ray Diffraction, room and low temperature Photoluminescence, Raman Scattering, and Atomic Force Microscopy. Growth of bulk GaInAs, single GaInAs quantum wells, and GaInAs/InP superlattices (including results on the shortest period, high quality GaInAs/InP superlattices prepared to date by OMVPE) are presented. Finally, a qualitative model relating accumulated interface roughness and preferential Group III incorporation during GaInAs nucleation is presented.
