Ultrahigh Electrostrictive Effect in Lead-Free Ferroelectric Ceramics Via Texture Engineering

Dragan Damjanovic, Li Jin, Yuan Sun

The electrostrictive effect, which induces strain in ferroelectric ceramics, offers distinct advantages over its piezoelectric counterpart for high-precision actuator applications, including anhysteretic behavior even at high frequencies, rapid reaction ti ...

Controlled Charging of Ferroelastic Domain Walls in Oxide Ferroelectrics

Tomas Sluka, Li Jin, Ludwig Feigl, Barbara Maraston Fraygola, Xiankui Wei

Conductive domain walls (DWs) in ferroic oxides as device elements are a highly attractive research topic because of their robust and agile response to electric field. Charged DWs possessing metallic-type conductivity hold the highest promises in this aspe ...

Polar lattice vibrations and phase transition dynamics in Pb(Zr1-xTix)O-3

Dragan Damjanovic, Li Jin

Infrared (IR) reflectivity spectra of nominally pure Pb(Zr1-xTix)O-3 ceramics with different Ti/Zr concentration (x = 0.42-0.58) were measured and evaluated, along with the time-domain terahertz transmittance spectra in the temperature range 10 K-900 K. Th ...

Broadband Dielectric Response in Hard and Soft PZT : Understanding Softening and Hardening Mechanisms

Li Jin

Lead zirconate titanate (Pb(Zr1-xTix)O3 or PZT) ferroelectric ceramics have been widely used in transducers, actuators, and sensors, since they posses high dielectric and piezoelectric properties with a relatively high temperature of operation. Commerciall ...

Lattice dynamics and dielectric response of undoped, soft and hard PbZr0.42Ti0.58O3

Dragan Damjanovic, Li Jin, Viktor Porokhonskyy

In this study, ceramic samples of lead zirconate titanate Pb(Zr0.42Ti0.58)O3 (PZT 42/58) doped with Fe (hard) and Nb (soft) were studied by Raman, infrared (IR) and THz spectroscopy in the temperature range from 900 to 20 K. From the evaluation of the IR a ...

What Can Be Expected From Lead-Free Piezoelectric Materials?

Dragan Damjanovic, Li Jin, Naama Klein, Viktor Porokhonskyy

The reasons for the lower piezoelectric properties in the most studied lead-free piezoelectrics, modified (K,Na)NbO3 and (Bi0.5Na0.5)TiO3, are discussed. Contributions from domain wall motion and properties at the morphotropic phase boundary are considered ...

Determination of three-dimensional orientations of ferroelectric single crystals by an improved rotating orientation x-ray diffraction method

Li Jin, Zhuo Xu

X-ray diffraction (XRD) techniques are widely used in determining crystallographic orientations. In this paper we describe a two-step method to determine the three-dimensional orientations of ferroelectric single crystals based on an improved rotating orie ...

Separation of piezoelectric grain resonance and domain wall dispersion in Pb(Zr,Ti)O-3 ceramics

Dragan Damjanovic, Li Jin, Viktor Porokhonskyy

We report on the experimental investigation of a high-frequency (1 MHz-1.8 GHz) dielectric dispersion in unpoled and poled Pb(Zr,Ti)O-3 ceramics. Two overlapping loss peaks could be revealed in the dielectric spectrum. The linear dependence between the low ...

Nanodomains in Fe[sup +3]-doped lead zirconate titanate ceramics at the morphotropic phase boundary do not correlate with high properties

Dragan Damjanovic, Li Jin

Configuration of domain walls in undoped and Fe+3-doped lead zirconate titanate (PZT) ceramics at the morphotropic phase boundary has been investigated by the transmission electron microscopy. The distance between domain walls in undoped PZT is on the orde ...
