AbstractWhen an electric field is applied to a ferroelectric the crystal lattice spacing changes as a result of the converse piezoelectric effect. Although the piezoelectric effect and polarization switching have been investigated for decades there has been no direct nanosecond-scale visualization of these phenomena in solid crystalline ferroelectrics. Synchrotron x-rays allow the polarization switching and the crystal lattice distortion to be visualized in space and time on scales of hundreds of nanometers and hundreds of picoseconds using ultrafast x-ray microdiffraction. Here we report the polarization switching visualization and polarization domain wall velocities for Pb(Zr0.45Ti0.55)O3 thin film ferroelectric capacitors studied by time-resolved x-ray microdiffraction.

Key Parameter

Understanding and measuring the displacement characteristics of piezoelectric ceramic with electric field exciting are particularly important. The piezoelectric coefficient d33 as the indication of its displacement characteristics, is the key parameter of its energy transformation. In this paper, the characteristics of two kinds of piezoelectric ceramics, PZT4 and PZT5 were studied by the laser interferometer measurement. The influence factors of d33 were studied, including the frequency and amplitude of the exciting signal, the ways of holding, and the loading sequence. Then the measurement results of piezoelectric ceramic with laser interferometer and the quasi-static method were compared, the results showed they had consistence and the analysis of the piezoelectric coefficient d33 measurement by converse piezoelectric effect and by piezoelectric effect was discussed.

Converse Piezoelectric Effect

Based on the traditional piezoelectric effect theory, the process of multi-piezoelectric effects generation is analyzed and the theory of the secondary and tertiary piezoelectric effect is deduced by four kinds of piezoelectric equations. Experimental research is performed through the PZT-5 piezoelectric ceramics stack, the existence of multi-piezoelectric effects is verified and experimental data is obtained under certain boundary conditions. The experimental data results show that if an external force which is applied to the positive piezoelectric effect is 400, the displacement generated by the secondary converse piezoelectric effect is 0.16. Therefore, starting from the first positive piezoelectric effect of the piezoelectric ceramics under applied force, the displacement generated by the secondary converse piezoelectric effect and the voltage generated by the tertiary positive piezoelectric effect are all linear with the applied force.

Converse Piezoelectric Effect

Photostrictive materials are lanthanum-modified lead zirconate titanate (Pb, La)(Zr, Ti) O3 ceramics doped with WO3, called PLZT, exhibit large photostriction under uniform illumination of high-energy light. Photostrictive materials are ferrodielectric ceramics that have a photostrictive effect. Photostriction arises from a superposition of the photovoltaic effect, i.e. the generation of large voltage from the irradiation of light, and the converse-piezoelectric effect, i.e. expansion or contraction under the voltage applied. When non-centrosymmetric materials, such as ferroelectric single crystals or polarized ferroelectric ceramics, are uniformly illuminated, a high voltage, considerably exceeding the band gap energy, is generated. Along with this photovoltage, mechanical strain is also induced due to the converse piezoelectric effect. Photostrictive materials offer the potential for actuators with many advantages over traditional transducing electromechanical actuators made of shape memory alloys and electroceramics (piezoelectric and electrostrictive). Drawback of traditional actuators is that they require hard-wired connections to transmit the control signals which introduce electrical noise into the control signals; on the other hand PLZT actuators offer non-contact actuation, remote control, and immune from electric/magnetic disturbances. Some experimental research has been conducted on the use of PLZT materials, such as optical motor as an electromechanical device suitable for miniaturization, micro-waking machine, photo driven relay device using PLZT bimorphs and high speed (less than 10 ns), low-voltage, low power consumption optical switch. Authors have developed a computational method and implemented in an in-house finite element code which will be useful for designing systems incorporating thin film photostrictive actuators. The purpose of this current research work is to design and develop an experimental test set-up for photostriction effect measurement of PLZT thin film of different thickness, size and location on silicon wafer as smart beams, which may be useful for various MEMS device as optical actuator. The experimental results will be verified by comparing with the FEA modeling results.

Converse Piezoelectric Effect

AbstractIn this study, the use of a fiber optic technique for the measurement of the piezoelectric properties of ferroelectric bulk and thin film samples was investigated. The strain and piezoelectric properties (namely the d33 coefficients) were measured using the MTI-2000 Fotonic Sensor, which uses the principle of the optical lever to resolve very small changes in sample displacement (1 Å). Using this technique, we were able to detect the very small strains associated with the converse piezoelectric effect for PVDF films and bulk PZT samples, and correlate the results with data acquired from direct piezoelectric effect measurement. Comparison of the data sets prove that the optical lever would be a useful optical technique for measuring of the d33 values of ceramic thin films, such as BaTiO3, ZnO, and PZT.
