abstract = {Epitaxial films composed of (Y,Sr)CoO3-δ and nano-scale
Y2O3 columns are successfully grown on
(La0.289Sr0.712)(Al0.633Ta0.356)O3(001) substrates at 900
°C. The microstructural and electrical properties of the
composite films are investigated and compared with those of
the single-phase films prepared at 800 °C. In the composite
films oxygen vacancies are detectable, which occur
alternately in the stacking CoO2-δ planes of (Y,Sr)CoO3-δ.
In addition, it is found that a large number of misfit
dislocations distribute at the interfaces between the Y2O3
columns and the (Y,Sr)CoO3-δ film matrix. The measured
resistivity of the composite films is significantly lower
than that of the (Y,Sr)CoO3-δ single-phase films. Our
results indicate that the electrical properties of the
perovskite-based cobaltates films can be tuned by changing
the microstructure through controlling the film-growth
temperature.},
