Abstract
The near-normal-incidence, room-temperature reflectance spectra of the - semiconductor alloy system have been measured for photon energies eV. Synchrotron radiation has been used to extend the measurements to 30 eV for . These spectra are similar to those of III-V compounds. Comparison of the primary, reflectance data with the results of others and with the band-structure calculations has been made. The reflectance has been analyzed via the Kramers-Kronig relations. We report curves for , , , , and for all the alloys studied. Strong structure in the fundamental absorption scales approximately linearly with alloy composition. Structure at 11 eV is associated with Cd -band excitation.
