    • Abstract

       

      Lattice imaging technique of high resolution electron microscopy has been employed to examine 4H, 6H and 9R ABO3 perovskite polytypes. The lattice images can be correlated with the lattice periodicity and the stacking sequence of AO3 layers and BO6 octahedra. The study shows the utility and validity of the lattice imaging technique for the study of relatively close-packed systems.
