abstract = {Both LaBaCo2O5.5+δ (LBCO) thin films and Co3O4
nanocrystals have potential applications in clean energy
storage and ethanol gas detection. Herein, we report that
the composite films of LaBaCo2O5.5+δ (LBCO) and {111}
faceted Co3O4 nanoparticles were fabricated on
(La,Sr)(Al,Ta)O3 (LSAT) and SrTiO3 (STO) substrates by
magnetron sputtering deposition. The LBCO films revealed an
epitaxial growth on both substrates with atomically sharp
interfaces and a cubic-on-cubic orientation relationship.
The Co3O4 particles were found to form at a very early stage
of the film deposition and have the orientation relationship
of [100]Co3O4//[100]LBCO and (100)Co3O4//(100)LBCO with the
LBCO film matrix. It was found that the size and density of
the Co3O4 particles can be tuned using different substrates,
which induces different strains in the films. By means of
high-resolution scanning transmission electron microscopy,
the 3-dimensional morphology of the Co3O4 particles was
illustrated. The formation and growth of the Co3O4 particles
are discussed with respect to the strains of the films
induced from the substrates.},
