Exploring Domain Switching Dynamics and Phase Configuration in Ferroelectrics

In situ synchrotron diffraction study will be used to identify and track multiple phases in single crystals of the mixed perovskite PIN-PMN-PT as a function of electric field and external mechanical stress in dynamic mode. We we will exploit the unique capabilities of the BM28 beamline to perform X-ray dynamic diffraction in operando with a synchronized piezoelectric response and potential preparation for optical transmittance experiment which is critical to further the understanding of the ferroelectric phase transition and correlation to the dynamic domain re-configuration. The data will provide critical information in understanding the phase morphology during the phase transition, elucidate any additional intermediate phases during the switching process and ultimately provide a path towards optimization of this technologically important materials and transient effects.
