D. Debowska et al., LIQUID-NITROGEN AND ROOM-TEMPERATURE REFLECTIVITY SPECTRA OF CD1-XFEXSE IN THE 0.5-6.0-EV ENERGY-RANGE, Acta Physica Polonica. A, 86(6), 1994, pp. 1015-1020
The reflectivity measurements for mixed crystals Cd1-xFe(x)Se (0.00 le
ss-than-or-equal-to x less-than-or-equal-to 0.10) have been carried ou
t in an energy range of 0.5-6.0 eV at 300 and 77 K. The influence of F
e2+(3d6) states on the changes in the energy positions of the reflecti
vity maxima E0, E1(A1), E1(A2), and E1(B) is analyzed and the obtained
results are consistent with the models existing in the literature.
