Optical measurements of Cu(In1-xGax) 5Se8 were performed at room temperature in the photon energy range from 0.8 to 4.7 eV. Spectral dependence of the complex dielectric functions was derived. The structures observed in the measured spectra have been analyzed by fitting the second derivative of the experimental spectrum to analytical line shapes and have been attributed to the interband transitions E0, and E1A. The energies corresponding to the electronic transitions as well as the parameters as strength and broadening were determined. Besides, the values of E0 and E1A are found to increase linearly with increasing Ga content. |
