Abstract
A highly ordered grating pattern is observed in the SrRuO3buffer layer in an SrTiO3/SrRuO3bilayer system on (0 0 1) SrTiO3substrate. By means of high-resolution transmission electron microscopy, the grating lines are found to consist of lattice defects and nanoscale precipitate particles. The particles are identified as pure ruthenium crystals. Correspondingly, Sr-rich Ruddlesden-Popper planar defects occur in the nearby area. This unusual film growth phenomenon may provide a novel way to fabricate ordered structures in oxide films for potential applications.
