The Many-body optical gain in CdZnO/MgZnO quantum well (QW) structures with spontaneous and piezoelectric polarizations are investigated by using the non-Markovian gain model with many-body effects. As the Cd composition increases, the sign change of the internal field is observed and the bottom of the potential well in the conduction band is shown to exist on the right side in the well. The CdZnO/MgZnO QW structure with high Cd composition is found to have smaller optical gain because the strain-induced piezoelectric polarization and the spontaneous polarization in the well increase with the inclusion of Cd.
