Optical signatures of defects in BiFeO
Sabine Körbel
Optical absorption in rhombohedral BiFeO starts at photon energies below the photoemission band gap of 3 eV calculated from first principles. A shoulder at the absorp…
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…
Transition between large and small electron polaron at neutral ferroelectric domain walls in BiFeO
Sabine Körbel, Jirka Hlinka, Stefano Sanvito
Ferroelectric domain walls are planes within an insulating material that can accumulate and conduct charge carriers, hence the interaction of the domain walls with the charge carri…
Erratum: Photovoltage from ferroelectric domain walls in BiFeO
Sabine Körbel, Stefano Sanvito
In the original article a mistake in the methodology lead to an incorrect prediction of exciton delocalization below a critical exciton density. This unrealistic delocalized excito…
Electron trapping by neutral pristine ferroelectric domain walls in BiFeO
Sabine Körbel, Jirka Hlinka, Stefano Sanvito
First-principles calculations for pristine neutral ferroelectric domain walls in BiFeO reveal that excess electrons are selectively trapped by the domain walls, while holes are…
