    Electrophysical diagnostics of Ag/HfO2/ZnO/TiAu structures
    (Видавництво Львівської політехніки, 2012) Krajewski, T. A.; Smertenko, P. S.; Luka, G.; Wachnicki, L.; Cherevko, A.; Olkhovik, G.; Zakrzewski, A. J.; Godlewski, M.; Guziewicz, E.
    This paper reports on the Ag/HfO2/ZnO/TiAu Schottky structures, in which the semiconducting ZnO and HfO2 layers are obtained using the low temperature Atomic Layer Deposition (ALD) method. Basing on the thermionic emission, differential and injection approaches an optimal thickness of HfO2 capping layer for the ZnO-based diode was found to be about 2.5 nm.

    Some properties of thin film structures on the base of ZnO obtained by MOCVD method
    (Видавництво Львівської політехніки, 2012) Roshchina, N. M.; Smertenko, P. S.; Stepanov, V. G.; Zavyalova, L. V.; Lytvyn, O. S.
    This paper reports on the ZnO film structures obtained by MOCVD method on Si substrates. The phase composition, structure and morphology of ZnO films as well as electrophysical properties of ZnO/Si heterojunction on their base were investigated. The possible charge flow mechanisms in ZnO/Si heterojunction are discussed.

    Tetraalkylammonium hydroxide template effects in electrodeposited nanostructured ZnO layers
    (Видавництво Львівської політехніки, 2012) Sydorov, D. A.; Mykhailov, S. D.; Motronyuk, T. I.; Piryatinski, Yu. P.; Smertenko, P. S.; Pud, A. A.
    We present here results of spectral (UV-Vis, PL), morphological (XRD, SEM) and voltammetric (I-V) characterizations of electrochemically deposited nanostructured ZnO layers at transparent ITO electrodes. For the first time the deposition was run in a presence of tetraalkylammonium hydroxides (TAAHs) as organic templates for comparison with the known one dye eosin Y. We find that the spectral and electrophysical properties of the ZnO layers synthesized when using the both types of the templates are quite similar that suggests applicability of TAAHs for the synthesis of nanostructured ZnO.
