Transmission electron microscopy study on domain structures in Bi3TiNbO9 ceramics

ABSTRACTA transmission electron microscopy study has been carried out on the domain structures of SrBi2Nb2O9 (SBN) ferroelectric ceramics which belong to the Aurivillius family of bismuth layered perovskite oxides. SBN is a potential candidate for Ferroelectric Random access memory (FeRAM) applications. The 90° ferroelectric domains and antiphase boundaries (APBs) were identified with dark field imaging techniques using different superlattice reflections which arise as a consequence of octahedral rotations and cationic shifts. The 90° domain walls are irregular in shape without any faceting. The antiphase boundaries are less dense compared to that of SrBi2Ta2O9(SBT). The electron microscopy observations are correlated with the polarization fatigue nature of the ceramic where the domain structures possibly play a key role in the fatigue- free behavior of the Aurivillius family of ferroelectric oxides.

Superconducting Compound

A transmission electron microscopy study has confirmed some new features of thermal variations of the microstructure in the high-T c superconducting compound YBa 2 Cu 3 O y. The changes of domain structures and the nucleation process of the tetragonal phase with the increase of temperature are demonstrated by series of images taken under in-situ heating observations. At temperature near 250°C, two new sets of planar defects have been observed along the directions of a and b-axes, respectively. It has been identified that a continuous structural phase transition, from orthorhombic to tetragonal phase, occurs at about 480 °C. The structural properties of the tetragonal phase have been studied at 700°C.
