Using EBSD to Map Domain Structures in Ferroelectrics

Electron backscatter diffraction (EBSD) has undergone a rapid transformation in the past 15 years from a curiosity and a minority interest into an important part of our arsenal of microstructure characterisation techniques. In this time, it has been very widely applied in metallurgy, especially in understanding the influence of processing on local crystallographic textures and on boundary populations. More recently, it has been used in a diverse range of different fields including semiconductors, ceramics, geological materials and even palaeontology. In this article we will show how EBSD can yield invaluable information about domain structures in ferroelectrics.
