  • Conductance and Photoconductance of Indium Oxide-Zinc Oxide Composites in the Hydrogen-Containing Atmosphere 
    ILIN, A. S.; FORSH, P. A.; IKIM, M. I.; KOROLEVA, A. V.; MARTYSHOV, M. N.; TRAKHTENBERG, L. I.; KASHKAROV, P. K. (Tehnica UTM, 2019)
    Photovoltaic properties of composites based on nanocrystalline indium and zinc oxides, promising as sensitive elements of gas sensors, were investigated. It is shown that under visible light the conductivity of composites ...
  • Effects of Heat Treatment on Palladium-doped Zinc Oxide on Sensory Selectivity 
    MAGARIU, N. (Tehnica UTM, 2019)
    In this paper I investigated the sensor response based on palladium-doped zinc oxide. How did the hydrogen and ethanol response change to a simple sensor that was not treated quickly and a heat treatment at 650 oC.
  • Enhancement in Conductivity and Photoresponse of Ga Doped ZnO Nanofibers 
    MARTYSHOV, M. N.; ILIN, A. S.; PLATONOV, V. B.; FORSH, P. A.; KASHKAROV, P. K. (Tehnica UTM, 2019)
    Nanofibers ZnO and ZnO:Ga with a diameter of 100-250 nm were obtained by electrospinning. Introduction of Ga impurity at a concentration of 1 at. % leads to a significant increase in the conductivity of ZnO nanofibers. It ...
  • Luminescent Properties on ZnO:Cr Nanocrystals and Thin Layers 
    GOGLIDZE, T.; DEMENTIEV, I.; GONCEARENCO, E.; NEDEOGLO, N.; IURIEVA, T.; NEDEOGLO, D. (Tehnica UTM, 2019)
    Both undoped and chromium doped zinc oxide nanocrystal powders are obtained by chemical deposition and hydrothermal methods. ZnO and ZnO:Cr thin layers on the surface of ZnSe and ZnSe:Cr samples, respectively, are obtained ...
  • ZnO Nanometric Layers Used in Photovoltaic Cells 
    BOTNARIUC, V.; GORCEAC, L.; COVAL, A.; CINIC, B.; GAUGAS, P.; CHETRUS, P.; LUNGU, I.; RAEVSCHI, S. (Tehnica UTM, 2019)
    The ZnO thin layers were grown on glass, InP and pInP-nCdS substrates from zinc acetate dissolved in water-acetic acid-methanol solution having a molarity of 0.2 M by using the spray method in the argon flow in the temperature ...
