Abstract

The electromechanical properties of [111]-oriented tetragonal Pb(In_1/2Nb_1/2O₃)-Pb(Mg_1/3Nb_2/3O₃)-PbTiO₃ (PIN-PMN-PT) crystals were investigated for potential high frequency ultrasonic transducers. The domain-engineered tetragonal crystals exhibit an ultrahigh free dielectric permittivity ϵ₃₃^T> 10 000 with a moderate electromechanical coupling factor k₃₃ ∼ 0.79, leading to a high clamped dielectric permittivity ϵ₃₃^S of 2800, significantly higher than those of the rhombohedral relaxor-PT crystals and high-K (dielectric permittivity) piezoelectric ceramics. Of particular significance is that the [111]-oriented tetragonal crystals were found to possess high elastic stiffness, with frequency constant N₃₃ of ∼2400 Hz m, allowing relatively easy fabrication of high-frequency transducers. In addition, no scaling effect of piezoelectric and dielectric properties was observed down to thickness of 0.1 mm, corresponding to an operational frequency of ∼24 MHz. These advantages of [111]-oriented tetragonal PIN-PMN-PT crystals will benefit high-frequency ultrasonic array transducers, allowing for high sensitivity, broad bandwidth, and reduced noise/crosstalk. © 2016 Author(s).
