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 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
