Description
Summary:The piezoelectric properties of Pb(In0.5Nb0.5)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 crystals with various engineered domain configurations were investigated. Rhombohedral and monoclinic/orthorhombic crystals poled along their crystallographic [011] directions were found to possess macroscopic mm2 symmetry, with “2R” and “1O” domain, respectively. Crystals with the “2R” domain configuration were found to exhibit high extensional piezoelectric coefficients d33 (∼1300 pC/N) and d32 (∼−1680 pC/N), while crystals with the “1O” configuration possessed high shear coefficients d15 (∼3500 pC/N) and d24 (∼2070 pC/N), with relatively low extensional piezoelectric coefficients d33 (∼340 pC/N) and d32 (∼−260 pC/N). The observed results were explained by “polarization rotation” model, as related to their respective domain configurations.
