Title: Real-Time Studies of Strains at Ferroelectric Domain Walls under an Applied Field
Published: August 17, 2002
Abstract: We report on an improved method of visualizing domains in congruent ferroelectric crystals such as LiNbO^d3 with Bragg x-ray topography. Using monochromatic synchrotron undulator radiation and a magnifying x-ray camera, we are able to image domains created by reverse poling, as well as the strain associated with the domains, in real time. With the application of an electric field, we observe unexpected domain wall deformations. Piezoelectric strains are also shown to create observable surface deformations. The deformations are precursors of 180 degree domain switching.
