Bent Ferroelectric Domain Walls as Reconfigurable Metallic-Like Channels

Alexander Tagantsev, Nava Setter, Igor Stolichnov, Tomas Sluka, Enrico Colla, Ludwig Feigl, Petr Yudin, Konstantin Shapovalov

Use of ferroelectric domain-walls in future electronics requires that they are stable, rewritable conducting channels. Here we demonstrate nontherrnally activated metallic-like conduction in nominally uncharged, bent, rewritable ferroelectric-ferroelastic ...

Identification of microscopic domain wall motion from temperature dependence of nonlinear dielectric response

Tomas Sluka

It is known that the permittivity of ferroelectric polydomain films and single crystals in weak electric fields is strongly enhanced by the reversible movement of pinned domain walls. Two mechanisms of the movement exist: first, the bending of free segment ...

Thickness Dependence of Domain-Wall Patterns in BiFeO3 Thin Films

Nava Setter, Silviu Cosmin Sandu, Tomas Sluka

Unique properties of domain walls in ferroelectrics have been recently discovered but methods of their controlled engineering remain underdeveloped. Here we investigate the domain structure of Bi0.9La0.1FeO3 epitaxial thin films with piezoelectric force mi ...

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

Nava Setter, Dragan Damjanovic, Alexander Tagantsev, 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 ...
