Nonlinear properties of lead zirconate–titanate piezoceramics
Nonlinear properties of lead zirconate-titanate ~PZT! piezoceramics are investigated using ultrasonic second harmonic generation technique. When a sinusoidal ultrasonic wave of frequency v0 is sent into a nonlinear material, the second harmonic wave with frequency 2v0 is generated. Through measuring the absolute amplitude of the fundamental (v0) and of the second harmonic (2v0) waves, the ultra...
متن کاملSubstrate clamping effects on irreversible domain wall dynamics in lead zirconate titanate thin films.
The role of long-range strain interactions on domain wall dynamics is explored through macroscopic and local measurements of nonlinear behavior in mechanically clamped and released polycrystalline lead zirconate-titanate (PZT) films. Released films show a dramatic change in the global dielectric nonlinearity and its frequency dependence as a function of mechanical clamping. Furthermore, we obse...
متن کاملA. Response of Lead Zirconate Titanate Ceramics to Temperature Fluctuations
It has been found that some shapes of lead zirconate titanate (PZT) ceramics respond to rapid temperature fluctuations when mounted in a particular geometrical configuration. This effect is presumably caused by thermal stresses in the crystal which produce a voltage difference across the silvered surfaces. These units were originally constructed to serve as pressure transducers in a lowpressure...
متن کاملFerroelectric Lead Zirconate Titanate and Barium Titanate Nanotubes
Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...
متن کاملMeasurement of Flexoelectric Effect in Lead Zirconate Titanate Ceramics*
Lead zirconate titanate (PZT) ceramics is usually used as a piezoelectric material. However it has characteristics of not only piezoelectricity but also flexoelectricity. Piezoelectricity is a phenomenon that electric polarization is induced by strain, and flexoelectricity is the one that the polarization is induced by strain gradient. In this study, flexoelectricity in poled soft PZT ceramics ...
