Under the application of an external voltage, high electric field concentrations can develop around the interdigitated electrode edges inside multilayer ceramic actuators (MLCAs). The spatial distribution of the local electrical field can create local inhomogeneity in the electromechanical response. We first study these spatially dependent effects by characterizing the crystal-orientation dependent response in monolithic samples of a Nb-doped PZT composition in close proximity to the morphotropic phase boundary (MPB) using in situ high-energy X-ray diffraction (XRD). In this initial study, we demonstrate that the field-induced phase transition from tetragonal to rhombohedral is dependent on crystal orientation, i.e. occurring preferentially in certain orientations. We then characterize the spatial dependence of domain switching and phase transitions in samples with partial electrodes, i.e. in which large electric field concentrations and inhomogeneity in electric field direction are expected. The domain switching behavior, both in amplitude and orientation, was found to be strongly spatially dependent in regions near the electrode edge. Specifically, the degree of domain alignment and field-induced phase transitions are amplified near the electrode edge. The orientation-dependent phase transitions are also amplified in compositions near the MPB. These results and insight are of high relevance to understanding the ferroelectric response near electrode edges and the nuances associated with field-induced phase transitions in polycrystalline ferroelectrics.
