Measuring Direct Flexoelectricity at the Nanoscale

open access: yesIEEE Electron Device Letters
Flexoelectricity is a property of all dielectric materials, where inhomogeneous strain induces electrical polarization. This effect becomes particularly prominent at the nanoscale where larger strain gradients can be obtained. While flexoelectric charges have been measured in mm-scale systems, direct measurements in nanoscale-thickness materials have ...

Influence of Flexoelectric Coupling and Interfacial Imperfection on Shear Horizontal Wave Propagation in a Piezoflexoelectric Layer over an Elastic Substrate

open access: yesMathematics
This study analytically investigates shear horizontal (SH) wave propagation in a layered structure consisting of a piezoflexoelectric (PFE) layer bonded to an elastic substrate, considering an imperfect interface.

Causal inference in statistics insights into stress-induced ferroelectric states in SrTiO: disentangling piezoelectric and flexoelectric effects from birefringence images

open access: yesScience and Technology of Advanced Materials: Methods
In materials science, experimental conditions are precisely controlled to ensure high reproducibility. This property is well suited for causal inference in statistics, yet its potential remains unrealized.

Flexoelectricity in nematic domain walls

open access: yesPhysical Review E, 2008
Flexoelectric effects are studied in the domain walls of a nematic liquid crystal device showing the Freedericksz transition. Walls parallel to the alignment direction have a strong twist distortion and an electro-optic effect dominated by e1-e3 is seen.

Defects-enhanced flexoelectricity in nanostructures

open access: yes, 2009
Recent studies show that low dimensional nanostructures may exhibit nonlocal electromechanical effects such as flexoelectricity. Despite the recent progress in nanostructure growth techniques imperfections such as defects are practically unavoidable ...

Flexoelectricity in liquid crystals: theory, experiments and applications

open access: yes, 2013
This book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid ...

Flexoelectric Effect in Biaxial Nematics

open access: yesActa Physica Polonica A, 2012
The flexoelectric (FE) effect provides a linear coupling between electric polarization and orientational deformation in liquid crystals. It influences many electrooptical phenomena and it is used in some bistable nematic devices. A statistical theory of dipole FE polarization in biaxial nematic liquid crystals is used to calculate temperature ...
