Ferroelectric Polycrystals: Structural and microstructural levers for property engineering via domain-wall dynamics
J. Schultheiß, G. Picht, J. Wang +4
Ferroelectrics have a spontaneous electrical polarization that is arranged into domains and can be reversed by an externally applied field. This high versatility makes them useful…
Multi-step stochastic mechanism of polarization reversal in orthorhombic ferroelectrics
Yuri A. Genenko, Maohua Zhang, Ivan S. Vorotiahin +5
A stochastic model of electric field-driven polarization reversal in orthorhombic ferroelectrics is advanced, providing a description of their temporal electromechanical response.…
Multi-step stochastic mechanism of polarization reversal in rhombohedral ferroelectrics
Yuri A. Genenko, Ruben Khachaturyan, Ivan S. Vorotiahin +4
A stochastic model for the field-driven polarization reversal in rhombohedral ferroelectrics is developed, providing a description of their temporal electromechanical response. App…
Domain wall-grain boundary interactions in polycrystalline Pb(Zr0.7Ti0.3)O3 piezoceramics
J. Schultheiß, S. Checchia, H. Uršič +5
Interactions between grain boundaries and domain walls were extensively studied in ferroelectric films and bicrystals. This knowledge, however, has not been transferred to polycrys…
Stochastic model of dispersive multi-step polarization switching in ferroelectrics due to spatial electric field distribution
Ruben Khachaturyan, Jan Schultheiss, Jurij Koruza +1
A stochastic model for polarization switching in tetragonal ferroelectric ceramics is introduced, which includes sequential 90°- and parallel 180°-switching processes and accounts…
Enhancement of the electrocaloric cooling by electric field reversal: simulation and experiment
Yang-Bin Ma, Nikola Novak, Jurij Koruza +3
An improved thermodynamic cycle is proposed, where the cooling effect of an electrocaloric refrigerant is enhanced by applying a reversed electric field. In contrast to conventiona…
