Description
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. copyright 1999 American Institute of Physics
