[摘要]：The vertical interface effect on the physical properties of epitaxial metal-oxide films is demonstrated. Self-assembled (BiFeO3)(0.5):(Sm2O3)(0.5) nanocomposite films are fabricated with three-dimensional heteroepitaxy having an ordered nanocolumnar structure on a large scale. The vertical interface effect on lattice parameters, dielectric properties, and leakage currents is investigated.
