Abstract

Photoreflectance spectra of Cd1-xMnxTe/CdTe superlattices with high compositions x = 0. 4,0. 8 were carried out at room temperature and liquid nitrogen temperature. The samples were grown by molecular beam epitaxy ( MBE) technique. Exciton transitions of heavy-and light-holes related to 11H,22H,33H and 11L were observed. After taking into consideration the strain-induced and quantum confinement effects, the theoretical calculations are in very good agreement with our photo-reflectance measurement results except 33H of x = 0.8. Photoluminescence spectra were also performed at room temperature and low temperature in order to compare with our photoreflectance results.
