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.

    Using a two-dimensional geometrical model and fractional dimension approach, it is found analytically that the ratio of the binding energy of a biexciton to that of an exciton is 0.228 in quantum wells and it is independent of the quantum-well width. This agrees very well with the results in...
