[摘要]：The piezoelectric properties of Pb(In0.5Nb0.5)O-3-Pb(Mg1/3Nb2/3)O-3-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 d(33) (similar to 1300 pC/N) and d(32) (similar to-1680 pC/N), while crystals with the "1O" configuration possessed high shear coefficients d(15) (similar to 3500 pC/N) and d(24) (similar to 2070 pC/N), with relatively low extensional piezoelectric coefficients d(33) (similar to 340 pC/N) and d(32) (similar to-260 pC/N). The observed results were explained by "polarization rotation" model, as related to their respective domain configurations. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3494532]
