Flexoelectricity in thin films and membranes of complex oxides

open access: yesAPL Materials, 2020
Flexoelectricity describes the generation of electric polarization in response to inhomogeneous strain, i.e., strain gradient, in all dielectrics. Importantly, strain gradients are inversely scaled to the material dimension so that more prominent and ...

Flexoelectric effect modelling [PDF]

open access: yesOpto-Electronics Review, 2008
AbstractA statistical theory of dipole flexoelectric (FE) polarization in liquid crystals is used to calculate temperature dependence of order parameters, elastic constants and FE coefficients. Two systems with polar wedge-shaped and banana-shaped molecules are investigated.

Verification of the flexoelectricity in barium strontium titanate through d33 meter

open access: yesAIP Advances, 2016
Flexoelectricity is a newly arising electromechanical property that couples strain gradient to polarization. This physical property widely exists in most of the solid dielectrics but has quite weak response that often overlooked.
