We have experimentally demonstrated the wave functions distribution of the lowest multiplet of states in symmetric triple quantum wells (QWs) using magneto-absorption measurements. In this experiment, we utilized the giant Zeeman splitting of band edges in diluted magnetic semiconductors (DMSs) to map out the wave functions of states. We fabricated two triple QW systems consisting of Zn1-x-yCdxMnySe (DMS) and Zn1-xCdxSe (non-DMS) wells, separated by ZnSe (i.e., non-magnetic) barriers. Transitions involving the lowest multiplet of states (i.e., the ground state split by inter-well interactions) were clearly observed and well resolved at zero magnetic field. By analyzing the Zeeman shift shown by each transition, we are able to demonstrate the probability of finding an electron in a given well.
