摘要：

Zn0.91Cd0.09Se/Zn0.82Mn0.18Se superlattices were grown by molecular beam epitaxy with well layer thicknesses of 4-35Angstrom and a barrier layer thickness of 12Angstrom. Magneto-luminescence was measured in the Faraday geometry in the temperature range of 10-100K. The Zeeman shifts of the excitonic emissions from the superlattices were analyzed as a function of well layer thickness by using Kronig-Penny model, in which the conduction and valence band offsets were modulated by external magnetic field. Paramagnetism enhancement of ZnMnSe at the interface with nonmagnetic layer and Mn diffusion at the heterointerface were taken into consideration. The Mn diffusion showed a crucial effect on the Zeeman shift of the superlattice system. (C) 2003 Elsevier Ltd. All rights reserved.
