  • Comparison of optical properties of TiO₂ thin films prepared by reactive magnetron sputtering and electron-beam evaporation techniques 
    Brus, V.V.; Kovalyuk, Z.D.; Parfenyuk, O.A.; Vakhnyak, N.D. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2011)
    The envelope method was used to determine optical constants of TiO₂ thin films deposited by DC reactive magnetron sputtering and electron-beam evaporation techniques. The density and thickness of the thin films were ...
  • Influence of Cr doping on optical and photoluminescent properties of CdTe 
    Ilashchuk, М.I.; Parfenyuk, O.A.; Ulyanytskiy, K.S.; Brus, V.V.; Vakhnyak, N.D. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2010)
    Spectra of transmission and low-temperature photoluminescence of CdTe:Cr crystals have been investigated for concentrations of the doping impurity (Cr) from 1∙10¹⁷ to 4∙10¹⁹ cm⁻³ in the melt. We have found additional ...
  • Influence of low-temperature annealing on the state of CdTe surface 
    Parfenyuk, O.A.; Ilashchuk, M.I.; Chupyra, S.M.; Burachek, V.R.; Korbutyak, D.V.; Krylyuk, S.G.; Vakhnyak, N.D. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    Influence of low-temperature annealing on electrical and luminescent properties of semi-insulating n-CdTe:Sn is studied. It is shown that annealing at T ≥ 453 K modifies a near-surface layer of the crystals and this enhances ...
  • Photoelectrical analysis of n-TiO₂/p-CdTe heterojunction solar cells 
    Brus, V.V.; Maryanchuk, P.D.; Parfenyuk, O.A.; Vakhnyak, N.D. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2013)
    Photoelectrical properties of n-TiO₂/p-CdTe heterojunction solar cells were investigated under different light conditions, taking into account the presence of series and shunt resistances. The effect of light dependent ...
