Abstract
Ferroelectric material properties are strongly governed by domain structures and their evolution processes, butthe evolution processes of complex domain patterns during a macroscopic electrical poling process are still elusive. Inthe present work, domain-evolution processes in a PZT ceramic near the morphotropic phase-boundary composition werestudied during a step-wise electrical poling using piezoresponse force microscopy (PFM). Electron backscatter diffractionwas used with the PFM data to identify the grain boundaries in the region of interest. In response to an externally theapplied electric field, growth and retreat of non-180° domain boundaries wasere observed. The results indicate thatferroelectric polarization-switching nucleates and evolves in concordance with the pattern of the pre-existing domains.
