Research Abstract

In order to truly understand the structure-property relationship of materials, structure under external stimuli must be investigated. In this research project, we have developed in-situ electron microscopy under external stimuli such as mechanical stress and electric field, and we have applied these techniques to some ceramic materials. The achievement includes direct observations of the dislocation motion and twin formations under mechanical stresses and the direct observations of domain movement in piezoelectric materials, and so on.
