Critical scattering of synchrotron radiation in lead zirconate-titanate with low titanium concentrations

Alexander Tagantsev

Diffuse scattering in the lead zirconate-titanate single crystal with a titanium concentration of 0.7 at % has been studied by the synchrotron radiation scattering method. Measurements have been performed both in the vicinity of the Brillouin zone center a ...

High Piezoelectric Longitudinal Coefficients in Sol-gel PZT Thin Film Multilayers

Paul Muralt, Andrea Mazzalai, Antonia Neels, Silviu Cosmin Sandu, Nachiappan Chidambaram, Alex Dommann, Davide Balma

A five-layer stack of lead zirconate titanate (PZT) thin films with Pt electrodes was fabricated for potential applications in nanoactuator systems. The 1 mu m thick PZT films were deposited by a sol-gel technique, the platinum electrodes by sputtering. Th ...

Comparison of Lead Zirconate Titanate Thin Films for Microelectromechanical Energy Harvester With Interdigitated and Parallel Plate Electrodes

Paul Muralt, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

Lead zirconate titanate (PZT) thin films on insulator-buffered silicon substrates with interdigitated electrodes (IDEs) have the potential to harvest more energy than parallel plate electrode (PPE) structures because the former exploit the longitudinal pie ...

Enhanced electromechanical response of ferroelectrics due to charged domain walls

Nava Setter, Dragan Damjanovic, Alexander Tagantsev, Tomas Sluka, Maxim Gureev

While commonly used piezoelectric materials contain lead, non-hazardous, high-performance piezoelectrics are yet to be discovered. Charged domain walls in ferroelectrics are considered inactive with regards to the piezoelectric response and, therefore, are ...

Comparison of lead zirconate titanate (PZT) thin films for MEMS energy harvester with interdigitated and parallel plate electrodes

Paul Muralt, Andrea Mazzalai, Nachiappan Chidambaram

PZT thin films on insulator buffered silicon substrates with interdigitated electrodes (IDEs) have the potential to harvest more energy than parallel plate electrode (PPE) structures, because IDE structures exploit the longitudinal piezoelectric effect, wh ...

Macroscopic Theory of Charged Domain Walls in Ferroelectrics

Maxim Gureev

This thesis consists of a theoretical analysis of charged domain walls in ferroelectrics based on Landau theory and the theory of semiconductors. First, the internal structure of a 180-degree charged domain wall is considered. It is shown that different re ...

Strain-modulated piezoelectric and electrostrictive nonlinearity in ferroelectric thin films without active ferroelastic domain walls

Dragan Damjanovic

In contrast to usual assumptions, it is shown that even when ferroelastic domain walls are inactive or absent, the motion of ferroelectrically active interfaces in ferroelectric materials contributes, at subcoercive electric fields, not only to the polariz ...
