The optical properties of cadmium arsenide are studied. Reliable new data on the reflection spectra are obtained owing to the use of perfect crystals and high-precision spectral equipment. The reflection spectra of the polymorphic modifications α(′′)-Cd"3As"2 (space group D 4h15) and α(′)-Cd"3As"2 (space group D4h11) are recorded at room and liquid-nitrogen temperatures in polarized light (E ⊥ c, E ∥ c) at incident-light photon energies of 1-5 eV. For the α(′) modification, anisotropy is observed in the reflection spectra for the first time. The obtained results are compared with the known experimental and theoretical data. |
