Physics and applications of charged domain walls

Alexander Tagantsev, Tomas Sluka, Petr Yudin, Petr Bednyakov

The charged domain wall is an ultrathin (typically nanosized) interface between two domains; it carries bound charge owing to a change of normal component of spontaneous polarization on crossing the wall. In contrast to hetero-interfaces between different ...

Free-Carrier-Compensated Charged Domain Walls Produced with Super-Bandgap Illumination in Insulating Ferroelectrics

Nava Setter, Alexander Tagantsev, Dragan Damjanovic, Tomas Sluka, Petr Bednyakov

Charged domain walls in ferroelectrics are movable and electronically conducting interfaces inside insulating materials. A simple and reliable method for their artificial production with ultraviolet (UV) light is described. The UV illumination produces fre ...

Formation of charged ferroelectric domain walls with controlled periodicity

Nava Setter, Dragan Damjanovic, Alexander Tagantsev, Tomas Sluka, Petr Bednyakov

Charged domain walls in proper ferroelectrics were shown recently to possess metallic-like conductivity. Unlike conventional heterointerfaces, these walls can be displaced inside a dielectric by an electric field, which is of interest for future electronic ...
