Confinement-driven inverse domain scaling in polycrystalline ErMnO3
Jan Schultheiß, Fei Xue, Erik Roede +5
The research on topological phenomena in ferroelectric materials has revolutionized the way we understand polar order. Intriguing examples are polar skyrmions, vortex/anti-vortex s…
Unveiling AC electronic properties at ferroelectric domain walls
Jan Schultheiß, Tadej Rojac, Dennis Meier
Ferroelectric domain walls exhibit a range of interesting electrical properties and are now widely recognized as functional two-dimensional systems for the development of next-gene…
Insulating improper ferroelectric domain walls as robust barrier layer capacitors
Lukas Puntigam, Jan Schultheiß, Ana Strinic +7
We report the dielectric properties of improper ferroelectric h-ErMnO. From the bulk characterisation we observe a temperature and frequency range with two distinct relaxation-…
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…
Intrinsic and extrinsic conduction contributions at nominally neutral domain walls in hexagonal manganites
J. Schultheiß, J. Schaab, D. R. Småbråten +5
Conductive and electrostatic atomic force microscopy (cAFM and EFM) are used to investigate the electric conduction at nominally neutral domain walls in hexagonal manganites. The E…
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…
