Abstract
Abstract The AC poling cycle dependence of Mn-doped Pb(Mg1/3Nb2/3)O3-0.3Pb(Zr.Ti)O3 (PMN-0.3PZT) single crystals (SC) produced via the solid-state crystal growth (SSCG) method was investigated. The piezoelectric strain and charge constants, d33 ＝ 1130 pC/N, g33 = 42.7 x 10-3 Vm/N, and mechanical quality factor Qm = 800 were obtained under conditions of 1 Hz, bipolar sine wave, 7.5 kV/cm electric field, and 6000 cycles.
In contrast to the conventional Bridgman process SC, the low-density and high Qm SSCG SC necessitates a substantial number of AC cycles due to the presence of pores within the SC.
In addition, the ACP SC showed a 13°C increase in the phase change temperature Trt compared to the DC-poled SC. This information of ACP SSCG SCs with improved thermal stability, low acoustic impedance, and enhanced receiving efficiency attributable to high g33 offers new insight into high-frequency ultrasonic devices.
