Domain formation and correlation effects in quenched uniaxial ferroelectrics: A stochastic model perspective
Olga Yu. Mazur, Yuri A. Genenko, Leonid I. Stefanovich
The stochastic analysis of the polarization domain structures, emerging after quenching from a paraelectric to a ferroelectric state, in terms of the polarization correlation funct…
Favorable band alignment for photocatalysis at the strontium germanate interface with silicon
Tomáš Rauch, Pavel Marton, Silvana Botti +1
Photocatalytic water splitting is a promising strategy for large-scale clean energy production. However, efficient and low-cost solid-state photocatalysts are still lacking. We pre…
Zig-zag charged domain walls in ferroelectric PbTiO
Pavel Marton, Mauro A. P. Gonçalves, Marek Paściak +5
We report a theoretical investigation of a charged 180 domain wall in ferroelectric PbTiO, compensated by randomly distributed immobile charge defects. For this we util…
First-principles based Landau-Devonshire potential for BiFeO
Pavel Marton, Antonín Klíč, Marek Paściak +1
The work describes a first-principles-based computational strategy for studying structural phase transitions, and in particular, for determination of the so-called Landau-Devonshir…
Evidence for dielectric aging due to progressive 180 domain wall pinning in polydomain Pb(Zr0.45Ti0.55)O3 thin films
Pavel Mokry, Yongli Wang, Alexander K. Tagantsev +3
An evidence that the dielectric ageing in the polydomain Pb(Zr0.45Ti0.55)O3 thin films is controlled by progressive pinning of 180 domain walls is presented. To provide such a conc…
A method to study ageing of polydomain ferroelectrics using measurements of nonlinear permittivity
Pavel Mokry
It is known that the permittivity of the ferroelectric films is affected by several phenomena, which deteriorate the material quality (e.g. the redistribution of the crystal lattic…
