Abstract
The room temperature reflectivity spectra of Cd1-xMnxTe mixed crystals for x up to 0.4 in the energy range from 1.5 to 14 eV have been investigated. A smearing out of the reflectivity maxima with growing x has been observed and attributed to manganese-induced chemical disorder. An additional structure at 4.6 eV interpreted as due to the transitions from the valence band to the Mn 3d6 states has been found. These results, together with previously published photoemission data, lead to the band picture of CdMnTe similar to the Adler-Feinleib type model proposed for transition metal chalcogenides with the correlation energy for d electrons of 9.6 eV.Keywords
