Abstract

High spatial resolution characterization of quantum wells has been performed by monochromatic cathodoluminescence imaging and by large angle convergent beam electron diffraction. The satellite lines to sublattice reflections which have been interpreted previously in terms of kinematical diffraction theory are here explored in detail by dynamical diffraction theory.
