Stability of tetragonal 〈001〉 oriented PZN-12PT single crystals
Source abstract
Abstract
The present paper reports on the synthesis and electromechanical characterization of tetragonal (1 − x)Pb(Zn1/3–Nb2/3)O3–xPbTiO3 (x = 12) single crystals as a function of various external disturbances. Tetragonal PZN-12PT single crystals were grown using the flux method. The set of piezoelectric coefficients in the lateral mode was measured. Samples with size of 10 × 2 × 1 mm3 were polled in the 〈0 0 1〉 and 〈1 1 0〉 crystallographic directions and were found to possess a high Curie temperature (>170 °C). Moreover, no ferroelectric–ferroelectric phase transition was observed for the positive temperatures, which expanded the usage range significantly. Tetragonal crystals were also found to have high coercive field, mechanical quality factors, and good optical properties, attracting much effort on the characterization of tetragonal PZN-12PT crystals. However, the most interesting properties in the lateral mode were obtained for 〈0 0 1〉. Finally, the thermal stability and stress dependence were studied in order to determine the working conditions.
