ABSTRACT

BaTiO3/SrTiO3 superlattices with embedded Ni nanocrystals (NCs) have been grown on SrTiO3 (001) substrate using laser molecular beam epitaxy (L-MBE). In situ reflection high-energy electron diffraction (RHEED) was employed to investigate the process of lattice strain in the self-organization of Ni NCs and the epitaxial growth of BaTiO3/SrTiO3 superlattices. The results indicated that the strain from large lattice mismatch drove the self-organization of Ni NCs. Also, the layer-by-layer growth of BaTiO3/SrTiO3 superlattices Keywords: Nanocrystal; Superlattices; Self-organization 1. Introduction Oxide artificial superlattices, especially (001) oriented BaTiOsuperlattices and the island growth of Ni NCs were controllable ac-curately. The fine alternation of the two processes would provide a possible route to engineer controllably the nano-composite microstructure.
