## Abstract The ellipsometric spectra of CuIn~3~Se~5~, CuGa~3~Se~5~ and CuGa~5~Se~8~ ordered vacancy compounds (OVC) have been studied in the spectral range from 0.8 to 4.4 eV. The structures observed in the measured spectra were analyzed by fitting the second derivative of the experimental spectru
## Abstract Optical absorption spectra of CuIn~5~Se~8~ and CuGa~3~Se~5~ single crystals have been investigated. The energy gap __E__ ~g~ for CuIn~5~Se~8~ (CuGa~3~Se~5~) was found to be varied from 1.27 (1.79) to 1.21 (1.71) eV in the temperature range between 10 and 300 K. The temperature dependenc
