abstract = {Epitaxial nano-scale LaBaCo2O5.5+δ (LBCO) islands are
prepared on (La,Sr)(Al,Ta)O3 (LSAT) substrates by pulsed
laser deposition technique. The microstructure of these
islands is investigated by aberration-corrected (scanning)
transmission electron microscopy. These islands exhibit
morphologies of truncated octahedron with {111}LBCO side
surfaces and form on nano-sized {111}Co3O4 faceted Co3O4
secondary phase that grows directly on the substrate. The
crystallographic orientation relationships between the LBCO
film and the LSAT substrate, as well as between the LBCO
film and the Co3O4 secondary phase are determined. The
atomic structure of the coherent interfaces between the
Co3O4 phase and the LBCO islands is revealed by the
atomic-resolution high-angle annular dark field images.
Based on the obtained structural results, the growth
mechanism of the islands is proposed and discussed.},
