    Optical absorption spectra of CuIn5Se8 and CuGa3Se5 single crystals have been investigated. The energy gap E g for CuIn5Se8 (CuGa3Se5) was found to be varied from 1.27 (1.79) to 1.21 (1.71) eV in the temperature range ...
  • LEVCENKO, S.; SYRBU, N. N.; NATEPROV, A.; ARUSHANOV, E.; MERINO, J. M.; LEÓN, M. (IOP Publishing, 2006)
    Single crystals of CuGa3Se5 have been grown by chemical vapour transport. Optical properties of CuGa3Se5 have been investigated in the temperature range between 10 K and room temperature 300 K. The temperature dependence ...
  • NATEPROV, A.; LEVCENCO, S.; SYRBU, N. N. (Institutul de Fizică Aplicată, AŞM, 2006)
    The investigation of the absorption coefficient spectra below the fundamental edge of ordered vacancy compound CuGa5Se8 was studied early for samples prepared by Bridgman method. Compositional measurements were carried out ...
  • ARUSHANOV, E.; LEVCENKO, S.; SYRBU, N. N.; NATEPROV, A.; TEZLEVAN, V.; MERINO, J. M.; LEÓN, M. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2006)
    Optical absorption spectra of CuIn5Se8 and CuGa3Se5 single crystals grown by chemical vapour transport were investigated in the range of 10–300 K. The logarithmic variation of the absorption coefficient with photon energy ...
