Abstract

The atomic structure of a planar defect with a (001) habit plane in single crystal layered perovskite SrBi₂Ta₂O₉ is determined by high-resolution Z-contrast imaging. We found that the defect forms a structure, with two Sr-Ta-O perovskite blocks connected by a metallic Sr₂ plane, rather than a Bi₂O₂ layer as in the perfect crystal. This defect is expected to be an efficient hole trap and may have important implications for the electronic properties and the ferroelectric response of the SrBi₂Ta₂O₉ material.
