Abstract
The band structure of semimagnetic type-III quantum wells (QW’s) has been calculated using an eight-band model in an envelope function approach. Details of the band structure calculations are given for the Mn-free case . A mean-field approach is used to take the influence of the exchange interaction on the band structure of QW’s with low Mn concentrations into account. The calculated Landau level fan diagram and the density of states of a QW are in good agreement with recent experimental transport observations. The model can be used to interpret the mutual influence of the two-dimensional confinement and the exchange interaction on the transport properties of QW’s.
