Abstract

The piezoelectric property of hypothetic single-crystal PbZr1-x Tix O3 (PZT) is studied using phase-field simulations. The dependence of piezoelectric coefficient (d3) on PbTiO3 compositions (x) near the morphotropic phase boundary of PZT was obtained. Using the existing thermodynamic description of PZT, it is shown that d3 reaches a peak value of 720 pC/N at x=0.47 which is more than three times of that for the ceramic counterpart. The relation between the domain structure of the poled PZT single crystals and the enhancement of d33 near the MPB composition is discussed.
