Résumé
The object of this work is to investigate crystal orientation‘s effects on electronic 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.
