摘要：

In this letter, we present our investigation of transverse piezoelectric performance in 0.70Pb(Mg1/3Nb2/3)O-3-0.30PbTiO(3) (0.70PMN-0.30PT) single crystals with different cuts using a resonance technique. We give the report on the finding of ultrahigh k(31) and d(31) values of 95.4% and -2517 pC/N, respectively. However, this unusual transverse piezoelectric property is only obtained in crystals with the polarization (thickness) and vibration (length) directions along the <110> and <001> directions, respectively. The 0.70PMN-0.30PT crystal with this cut shows significantly great potential for applications in high-performance transverse-mode piezoelectric devices, such as medical array ultrasonic transducers and actuators.
