Growth and interface characterization of GaAs/GaAlAs superlattices

Abstract
The growth conditions of multi-quantum wells (MQWs) and superlattices (SLs) have been optimized and the characterization of the interface of high quality GaAs/GaAlAs and GaAs/AIAs superlattices has been performed. Electron microscopy, luminescence and X-ray diffraction show interfaces flat within one monolayer and only very large growth islands
