In this study, the domain structure, bimodality of domains and wedge-shape formation of domain tips are investigated in tetragonal Pb[Zr0.375Ti0.625]O3 and Pb[Zr0.45Ti0.55]O3 ferroelectrics by transmission electron microscopy (TEM). Finite element method (FEM) calculations predicted the stability of the experimentally observed domain configuration for different boundary conditions concerning electrical...
Undoped Pb[ZrxTi1−x]O3 (PZT) ceramics from the tetragonal and rhombohedral side of the morphotropic phase boundary (MPB) were examined. Temperature dependent changes in domain configuration were observed by in situ hot-stage transmission electron microscopy (TEM). In corresponding macroscopic ex situ strain measurements an enhanced influence of the electric field was detected after annealing.
