Abstract:

Reflectivity spectra of CdGa2Se4, CdGa2S4 and CdAl2S4 crystals have been investigated in the range 1–6 eV for the polarization E∥c and E⊥c at 300 and 77 K. The valence band splitting caused by spin-orbital interaction and by crystal field are calculated for the point k = 0. The band model has been built in actual points of the Brillouin zone, Γ, N, T, P.
