Abstract: The morphotropic phase boundary (MPB) plays an important role in ferroelectric materials. Typically, two phases coexist in materials near the MPB. Such materials usually exhibit large piezoelectricities, dielectricities, and actuation strains. In this work, we produce an MPB-like effect in hybrid electrically poled, mechanically depolarized (HEPMD) BaTiO3 and lead zirconate titanate ceramics where depolarized region A and vertical electrically poled region C intersect each other with a period of 400 μm in both… Show more

“…Error bars depict the minimum, maximum, and mean values for each quantity. The red filled areas in Figure 7(a) to (c) represent the range of experimental data, taken from Enderlein (2007), Förderreuther (2003), and Wang and Li (2020). Having a look at the results of the remanent strain in Figure 7(a) the simulations are in a good accordance with experimental results independent of the number of MiMPs.…”

“…Mean values of (a) macroscopic remanent strain ε true¯ 22 r and (b) maximum strain ε true¯ 22 max taken from 10 simulations versus number of grains M and the lower limit of the domain volume fractions ν min . Red areas match the scope of experimental data (Enderlein, 2007; Förderreuther, 2003; Wang and Li, 2020). …”

“…First discovered in the lead zirconate titanate (PbZr x Ti 1– x O 3 ) material system, the concept of MPB has led to the discovery of relaxor ferroelectrics that exhibit 10-folds higher piezoelectric response than standard piezoelectrics. , The existence of MPB in Sm-substituted BFO and its enhanced electromechanical properties near MPB have been reported . Also, there is evidence of enhancement in the piezoelectric response of ferroelectrics driven by polarization rotation or domain switching under an externally applied field. An open question is whether enhanced piezoelectricity near MPB can facilitate polarization switching at lower switching voltage in the material. Wang et al reported the possibility of easy domain switching near the MPB; however, additional support from other literature is scarce.…”
