Zeeman effect in CdMnTe parabolic and half parabolic quantum wells


We have investigated the electronic structure of Cd1􀀀xMnxTe parabolic quantum wells and half- parabolic quantum wells heterostructures in the envelope function approximation using the k p method. We have considered an external magnetic eld applied in two di erent con gurations: in the plane of the layer and in the growth direction. The con ned states have been calculated taking into account the e ective mass dependence of the Mn concentration and the strain e ects. In this work we analyze the giant Zeeman splitting due to applied magnetic elds and we have compared the energies of the excitonic transitions hh (lh) ! el for the magnetic eld in the two considered con gurations. Comparison of our results for the half-parabolic quantum wells with available experimental data is made.
