Abstract

The enhanced Zeeman effect of excitons in asymmetric CdZnTe-CdTe-CdMnTe quantum wells is studied quantitatively to gain information separately on the profile of the normal and inverted interfaces. The normal interface appears as more “abrupt” than the inverted interface. This behaviour is well accounted for if we assume that during the growth a rapid Cd/Mn exchange takes place between the surface layer and the subsurface one.
