摘要

We studied the microstructure of SrTiO_3/SrRuO_3 bilayer films on(001)LaAlO_3 substrates by high-resolution transmission electron microscopy. At the SrRuO_3/LaAlO_3 interface a defect configuration of stacking faults and nanotwins bounding either Frank partial dislocations or Shockley partial dislocations and complex interaction between these planar defects were found to be the dominant means of misfit accommodation. The misfit in the SrTiO_3/SrRuO_3 system, however, is mainly accommodated by Elastic strain.
