摘要：

Strained CdTe/(Cd,Mn)Te-MQW structures, grown by MBE on InSb substrates, are investigated by luminescence and reflection spectroscopy. Free and donor-bound (D0X) exciton and donor-acceptor-pair (DAP) transitions are studied in dependence on magnetic field strength and orientation. The D0X binding energy is found to decrease with increasing magnetic field. Magnetic polaron effects are observed both for D0X and DAP transitions. In the case of D0X spin-pinning with respect to the normal axis of the quantum wells is seen. A discussion of the results on the basis of a Kronig-Penney model calculation taking into account the strain effects yields a large valence band offset, and a valence/conduction band offset ratio of 1.6 to 1.8 is determined.
