Optical properties of ZnSe/(Zn,Mn)Se multiquantum wells

Abstract
Luminescence, excitation, and reflectance spectroscopy have been employed to study the exciton ground state in ZnSe/(Zn,MnSe) multiquantum wells. We find that the ground state shows splittings which are attributed to the superlattice layer strain. The measured large magneto-optical shifts and splittings indicate that the valence-band discontinuity is likely to be quite small in these structures.
