More details: The optical absorption spectra of the ordered vacancy compound CuIn 4 Se 7 thin film have been$\backslash$nanalysed with special consideration to the threefold optical structure at the fundamental gap. The$\backslash$nthin films for this study have been prepared by vacuum co-evaporation and the structural and$\backslash$ncompositional characterization done using x-ray diffraction in conjunction with energy dispersive$\backslash$nx-ray analysis. The quasi-cubic model adapted for crystals with tetragonal distortion has been used$\backslash$nto determine the crystal field splitting and spin?��orbit splitting parameters. The effects of p?��d$\backslash$nhybridization and structural changes on the parameters are explained. The percentage of$\backslash$nhybridization of the orbitals is determined using the linear hybridization model.
