  • Abstract
    In the present paper the excitonic reflectivity and the wavelength derivative reflection (WDR) study of CuGaxInx-1Se 2 solid solutions are presented. The states n=1, n=2 and n=3 of A, B, C exciton series are determined. The exciton binding energies and more exact values of the band gaps of all three intervals (Γ 7V1-Γ6C1, Γ6V2-Γ6C1, Γ7V3-Γ6C1) are calculated hereby. The magnitudes of the splitting due to crystal-field and spin-orbit interaction are determined as well
