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…
Dielectric and electro-mechanic nonlinearities in perovskite oxide ferroelectrics, relaxors and relaxor ferroelectrics
Lukas M. Riemer, Li Jin, Hana Uršič +3
The polarization and strain response of ferroelectric materials at fields below the macroscopic coercive field is of a paramount importance for the operation of many electronic dev…
Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials
Andreja Bencan, Emad Oveisi, Sina Hashemizadeh +6
The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery o…
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…
