    (2015-11-26) Hebal Hamza; Encadreur: Abid Hamza
    Résumé (Français et/ou Anglais) : The object of this work is to investigate crystal orientation‘s effects on electronic optical properties of wurtzite CdZnO/ZnO quantum wells (QWs) with piezoelectric (PZ) and spontaneous (SP) polarization using the multiband effective-mass theory and the non-Markovian gain model with many-body effects. In this research, we address the electronic and the optical properties of wurtzite CdZnO grown on ZnO substrate, the valence -band structures for the QW structure are calculated based on the k.p method .The results will be confronted with those of WZ GaN/InGaN QW structures and also similar studies.
