How to Make Elastomers Piezoelectric?
Piezoelectrics play a significant role in modern electronics and electric devices. Thermal or mechanical stress on such materials induces a change in polarization generating an electric response, which is the sole effect of why they are so interesting. How ...
WILEY2023Induced giant piezoelectricity in centrosymmetric oxides
Paul Muralt, Dragan Damjanovic, Vasiliki Tileli, Mahmoud Hadad, Lukas Riemer, Daesung Park
Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric materials must have a noncentrosymmetric crystal structure. For more than a century, this has remained a major obstacle ...
2022Nonlinear electro-mechanical coupling and thermally stimulated currents in relaxor ferroelectrics
In this work, the emergence of polarization and electro-mechanical coupling in Pb(Mg1/3Nb2/3)O3 and Pb(Mg1/3Nb2/3)O3 â PbTiO3 was investigated by means of thermally stimulated current, and nonlinear dielectric and electro-mechanical measurements. The pre ...
EPFL2022Optimization of the fabrication of buried electrodes for NEMS resonators
The aim of this project is to optimize the fabrication of buried lateral electrodes, with a piezolectric material sandwiched between two metal electrodes. Lateral electrodes have the advantage of allowing the applied electric field to be and to remain comp ...
2021Individual Barkhausen pulses of ferroelastic nanodomains
Dragan Damjanovic, Vasiliki Tileli, Reinis Ignatans
Ferroelectric materials, upon electric field biasing, display polarization discontinuities known as Barkhausen jumps, a subclass of a more general phenomenon known as crackling noise. Herein, we follow at the nanoscale the motion of 90 degree needle domain ...
2020Macroscopic polarization in the nominally ergodic relaxor state of lead magnesium niobate
Dragan Damjanovic, Yang Li, Lukas Riemer, Kanghyun Chu, Brahim Dkhil
Macroscopic polarity and its dynamic response to external electric fields and temperature in the nominally ergodic relaxor phase of pristine lead magnesium niobate crystals and ceramics, Pb(Mg1/3Nb2/3)O3 (PMN), were investigated. Dynamic pyroelectric measu ...
2020Ferroelectric Self-Poling in GeTe Films and Crystals
Ferroelectric materials are used in actuators or sensors because of their non-volatile macroscopic electric polarization. GeTe is the simplest known diatomic ferroelectric endowed with exceedingly complex physics related to its crystalline, amorphous, ther ...
2019Characterization methodology for lead zirconate titanate thin films with interdigitated electrode structures
Paul Muralt, Robin Nigon, Trygve Magnus Raeder
The accurate evaluation of ferroelectric thin films operated with interdigitated electrodes is quite a complex task. In this article, we show how to correct the electric field and the capacitance in order to obtain identical polarization and CV loops for a ...
Amer Inst Physics2017Strain-induced polar discontinuities in two-dimensional materials from combined first-principles and Schrodinger-Poisson simulations
Giovanni Pizzi, Marco Gibertini, Augustin Bussy
The local application of mechanical stress in piezoelectric materials gives rise to boundaries across which the electric polarization changes. Polarization charges appear along such polar discontinuities and the ensuing electric fields drive a charge recon ...
Amer Physical Soc2017Heuristic Description of Magnetoelectricity of Cu2OSeO3
CuO2SeO3 is an insulating material that hosts topologically nontrivial spin whirls, so-called skyrmions, and exhibits magnetoelectric coupling allowing to manipulate these skyrmions by means of electric fields. We report magnetic force microscopy imaging o ...
