Title

Crystallographic Shear Planes And Stacking Disorders In Perovskites Knbo3 And Nanbo3

Abstract

The crystallographic shear planes and stacking faults with orientations parallel to the {100} and {111} pseudocubic lattice planes are observed in perovskite crystals by means of TEM. The translation vector is determined as 〈110〉/2 for the crystallographic planes, while the stacking disorder is just the planar faults at which the stacking order of the corner‐connected octahedra in the {111} plane are misarranged to form the so‐called face‐sheared octahedra. The existence of such two kinds of planar defects indicates that the transition or alkali metal atoms can easily migrate due to the large concentrations of oxygen vacancies in the perovskite at sufficiently high temperature.
