(Er:PMN-PT) single crystals with various compositions and phases was studied using Rayleigh analysis. High temperature poling process was introduced to optimize the piezoelectric properties of the [001]-oriented Er:PMN-PT crystals. The Rayleigh analysis results show that the intrinsic contribution was dominated to the piezoelectric properties for the Er:PMN-PT crystals. The intrinsic and extrinsic piezoelectric responses of the Er:PMN-

The piezoelectric response can be significantly enhanced by the high-temperature poling process, and the maximum was 2800 pC/N for the Er:PMN-0.29PT crystal. This ultra-high piezoelectric response was attributed to easing in the polarization rotation of the rhombohedral phase at high temperatures. |
