| dc.description.abstract | Interference spectra of layered ZnIn2S4 crystals were investigated for samples of different thicknesses (7.5–900 μm). Spectral dependences of refractive indices (na and nb) for light waves with different polarizations were calculated and their intersection observed at energy E0 ∼ 2.38 eV. The refractive indices difference (Δn = na − nb) was determined at energy range 0.8–3.0 eV. Features observed in reflection and absorption spectra were attributed to the band-to-band electron transitions at k = 0. Magnitudes of valence bands (V1, V2 and V3, V4) splitting due to crystal field and spin–orbital interaction were determined. Electron transitions in energy interval 2–6 eV were identified on the basis of available theoretical band structure calculations. | en_US |
