Complete set of elastic, dielectric, and piezoelectric coefficents of 0.93Pb(Zn1∕3Nb2∕3)O3–0.07PbTiO3 single crystal poled along [011]

The authors report a complete set of elastic, dielectric, and piezoelectric coefficients of rhomboheral phase 0.93Pb(Zn1∕3Nb2∕3)O3–0.07PbTiO3 single crystal poled along [011] measured at room temperature. It was found that the electromechanical coupling coefficients k32 and k33 of this domain engineered single crystal can reach 0.86 and 0.87, respectively, and the piezoelectric coefficients d32 and d15 are −1460 and 1823pC∕N, respectively. This complete set of data can meet the urgent need of device designers using these super piezoelectric crystals and also provide important information for fundamental studies on domain engineering.
