The piezoelectric property of hypothetic single-crystal PbZr1-xTixO3 (PZT) is studied using phase-field simulations. The dependence of piezoelectric coefficient (d33) on PbTiO3 compositions (x) near the morphotropic phase boundary (MPB) of PZT was obtained. It is shown that d33 reaches a peak of 720 pC/N at x = 0.47 which is more than 3 times of that for the ceramic counterpart. By analyzing the domain structure of the poled PZT single crystals, we can conclude that the enhancement of d33 near the MPB composition is attributed to the existence of multi-phase and multi-domain.
