Flexoelectricity in thin films and membranes of complex oxides
APL 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 ...

Towards a Bulk Theory of Flexoelectricity [PDF]
Physical Review Letters, 2010 Flexoelectricity is the linear response of polarization to a strain gradient. Here we address the simplest class of dielectrics, namely elemental cubic crystals, and we prove that therein there is no extrinsic (i.e. surface) contribution to flexoelectricity in the thermodynamic limit.

Flexoelectric effect on thickness-shear vibration of a rectangular piezoelectric crystal plate
Materials Research Express, 2021 Thickness-shear (TSh) vibration of a rectangular piezoelectric crystal plate is studied with the consideration of flexoelectric effect in this paper. The developed theoretical model is based on the assumed displacement function which includes the anti ...

Second-Order Collocation-Based Mixed FEM for Flexoelectric Solids
Solids, 2023 Flexoelectricity is an electromechanical coupling between the electric field and the mechanical strain gradient, as well as between the mechanical strains and the electric field gradient, observed in all dielectric materials, including those with ...

Flexoelectric effect modelling [PDF]
Opto-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.

Flexoelectric materials and their related applications: A focused review
Journal of Advanced Ceramics, 2019 Flexoelectricity refers to the mechanical-electro coupling between strain gradient and electric polarization, and conversely, the electro-mechanical coupling between electric field gradient and mechanical stress. This unique effect shows a promising size
