A structural grate pattern is observed in the SrRu03 buffer layer in a SrTi03/SrRuO3 bilayer system on (001) SrTi03 substrate. By means of high resolution transmission electron microscopy the grate fringes are identified as a band of planar defects with decoration of nanoscale precipitate particles. The planar defects are Sr-rich Ruddlesen-Popper defects occurring in the (100) and (010) planes. The precipitate particles are either Ru-rich phase or pure Ru crystals.
