Abstract:
In this letter, we present our investigation of transverse piezoelectric performance in 0.70Pb(Mg1∕3Nb2∕3)O3-0.30PbTiO3 (0.70PMN-0.30PT) single crystals with different cuts using a resonance technique. We give the report on the finding of ultrahigh k31 and d31 values of 95.4% and −2517pC∕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.
