Flexoelectric Fracture-Ratchet Effect in Ferroelectrics [PDF]

Physical Review Letters, 2019
The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate that, in piezoelectric materials, a consequence of flexoelectricity is that crack propagation is helped or hindered depending on whether it is parallel or antiparallel to the ...

Flexoelectric Suppression of Interfacial Carrier Loss in BaTiO3 Thin‐Film Bulk Photovoltaic Systems

Advanced Science, EarlyView.
In single‐crystalline BaTiO3 thin films, flexoelectric strain gradients strongly enhance photocurrent by suppressing interfacial carrier loss. Loading experiments reveal a ∼35‐fold photocurrent increase with applied force. Self‐consistent electrostatic modeling shows that strain gradients reshape the interfacial potential landscape, strengthen local ...

Flexomagnetic Effect in Wrinkled SrRuO3 Thin Films

Advanced Electronic Materials, EarlyView.
The strain‐gradient‐driven flexoelectric polarization can modify the magnetic moment of a magnetic film. In this work, SrRuO3 is grown epitaxially on a water‐soluble sacrificial layer Sr3Al2O6, thereby enabling the formation of wrinkled structures. The so‐called flexomagnetic effect is then observed in a wrinkled SrRuO3 film.

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Advanced Electronic Materials, Volume 12, Issue 16, 24 August 2026.
Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...
