The films were deposited on single crystals of yttria-stabilized zirconia (YSZ) in (100), (110) and (111) crystallographic orientations. The structural, mechanical and electrical properties of the films have been studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and nanoindentation and impedance spectroscopy methods. XRD and SEM results have shown that the films were polycrystalline. Effect of the substrate orientation on the microstructural, mechanical and electrical properties of CZY films has been examined. The films deposited on (110)-substrates consist of the largest grains; show the highest values of hardness and electrical conductivity. Conductivity of CZY film on (110)-substrates increases with rise in humidity which proves proton transport in the films |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ПЛЕНКИ -- ОСАЖДЕНИЕ -- СПЕКТРОСКОПИЯ -- ИМПЕДАНС Аннотация: CaZr0.9Y0.1O3 − δ films were fabricated by chemical solution deposition on single-crystalline YSZ (ZrO2 doped by 10 mol% of Y2O3) substrates. Mechanical hardness and morphology of the films were studied using nano-indentation and atomic force microscopy techniques. Grain microstructure of the films has been shown to depend upon thermal treatment duration and film thickness. Thin films with grains a few times greater than the film thickness have been obtained. It has been shown that thickness of films can be evaluated by comparing of the indentation curves for the clean and coated by the film substrates. Mechanical hardness of the film has been found to be sensitive to the film grain microstructure. Electrical behavior of CaZr0.9Y0.1O3 − δ films studied by impedance spectroscopy strongly depends on the film microstructure. |
T 44 The across-plane conductivity and microstructure of SrZr0.95 Y0.05 O3 − δ thin films / L. A. Dunyushkina, S. V. Plaksin , V. M. Kuimov, V. P. Gorelov, S. V. Smirnov // Ionics. - 2013. - Vol. 19, № 12. - P1715-1722. - Bibliogr. : p. 1722 (19 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ЭЛЕКТРОПРОВОДНОСТЬ -- СПЕКТРОСКОПИЯ -- ПРОВОДИМОСТЬ ПРОТОННАЯ Аннотация: The across-plane electrical conductivity of the proton-conducting SrZr0.95Y0.05O3 − δ thin films fabricated by chemical solution deposition on single-crystalline ZrO2 doped by 10 mol% of Y2O3 (YSZ) substrates was investigated using impedance spectroscopy. The average grain size of the films was found to increase considerably with thermal treatment. This change in grain size has a strong effect on the electrical behavior of films. Our results show that the electrochemical performance of the cell is strongly affected by the potential difference at the film/substrate interface. Coarse-grain film microstructure was proved to be preferable for the reduction of both the film resistance and interfacial barrier. |
