Abstract
Nanocomposite films, with Ni nanocrystals (NCs) (5–8 nm) embedded within SrTiO3/BaTiO3 superlattice (period: 30 nm), were prepared by laser molecular beam epitaxy. In situ reflection high-energy electron diffraction was employed to study the role of lattice strain in the self-organization of NCs and the epitaxial growth of SrTiO3/BaTiO3 superlattice. It was found that the strain from large lattice mismatch drove the self-organization of Ni NCs. Also the SrTiO3/BaTiO3 epitaxial growth was achieved on the NC-dotted irregular interface, because the epitaxial growth occurred preferably at sites with low strain. The fine alternation of the two processes would provide a possible route to engineer controllably the nanocomposite microstructure.
