Abstract:

Interference spectra of ZnIn2S4 crystals by 7.5 - 900 μm thicknesses were investigated. Spectral dependences of refractive indices (no and ne) were calculated and they intersection was observed at energy E0 ~ 2.8 eV. The spectral dependence Δn = no - ne at energy region 0.8 - 3.0 eV was determined.
