摘要：

We report on the growth by molecular beam epitaxy of II-VI semiconductor parabolic quantum wells. Cd1-xMnxTe diluted magnetic semiconductor was chosen for constructing these structures because of its extreme sensitivity to the presence of a magnetic field. Photoluminescence excitation spectra revealed several series of energetically equidistant peaks due to interband optical transitions. The energy separation in a given series scales proportionally to the inverse width of the quantum well as expected for a parabolic confining potential. Analysis of the spectra made possible a model-independent determination of the valence band offset in CdTe/Cd1-xMnxTe. (C) 1996 American Institute of Physics.
