“…These results are consistent with earlier results from tetragonal PZT. 25,26 For BNT-6.25BT, the initial structure is pseudo-cubic. On the application of the electric field, only the lattice strain is observed up to a critical field strength of around 2.5 kV/mm.…”

The electro-mechanical coupling mechanisms in polycrystalline ferroelectric materials, including a soft PbZrxTi1−xO3 (PZT) and lead-free 0.9375(Bi1/2Na1/2)TiO3-0.0625BaTiO3 (BNT-6.25BT), have been studied using a surface sensitive low-energy (12.4 keV) and bulk sensitive high-energy (73 keV) synchrotron X-ray diffraction with in situ electric fields. The results show that for tetragonal PZT at a maximum electric field of 2.8 kV/mm, the electric-field-induced lattice strain (ε111) is 20% higher at the surface than in the bulk, and non-180° ferroelectric domain texture (as indicated by the intensity ratio I002/I200) is 16% higher at the surface. In the case of BNT-6.25BT, which is pseudo-cubic up to fields of 2 kV/mm, lattice strains, ε111 and ε200, are 15% and 20% higher at the surface, while in the mixed tetragonal and rhombohedral phases at 5 kV/mm, the domain texture indicated by the intensity ratio, I111/I111¯ and I002/I200, are 12% and 10% higher at the surface than in the bulk, respectively. The observed difference in the strain contributions between the surface and bulk is suggested to result from the fact that surface grains are not constrained in three dimensions, and consequently, domain reorientation and lattice expansion in surface grains are promoted. It is suggested that the magnitude of property difference between the surface and bulk is higher for the PZT than for BNT-6.25BT due to the level of anisotropy in the strain mechanism. The comparison of the results from different methods demonstrates that the intergranular constraints have a significant influence on the electric-field-induced electro-mechanical responses in polycrystalline ferroelectrics. These results have implications for the design of higher performance polycrystalline piezoelectrics.

“…Diffraction images collected over multiple cycles are summed together and are represented with respect to a single cycle of the applied electric waveform. 20,21 Images were collected until sufficient statistics were obtained to allow the detection of the crystallographic changes in the material. For instance, under the bipolar electric field of 3 Hz, the sample was subjected to approximately 1.3 Â 10 5 electric field cycles, and images were collected for approximately 12 h in order to obtain sufficient diffraction statistics.…”

“…The change in the (111) peak positions were then used to calculate the time-dependent (111) lattice strain. 21 Figure 2 shows the time-dependent response of the (111) lattice strain to an applied bipolar electric field of frequency 3 Hz. When the positive polarity of the electric field cycle begins (0 s), the material displays an initially instantaneous strain response followed by a larger positive response for the remainder of the positive polarity of the electric field cycle.…”
