Enabling nanoscale flexoelectricity at extreme temperature by tuning cation diffusion

, 2018
Any dielectric material under a strain gradient presents flexoelectricity. Here, we synthesized 0.75 sodium bismuth titanate −0.25 strontium titanate (NBT-25ST) core–shell nanoparticles via a solid-state chemical reaction directly inside a transmission ...

A quantitative model of triboelectric charge transfer

Friction
Triboelectricity, when rubbing or contacting materials causes electric charge transfer, is ubiquitous across many fields, and has been studied in detail for centuries. Despite this, a complete description of triboelectricity remains elusive.

Piezoelectric mimicry of flexoelectricity

The origin of “giant” flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectriclike effects with parasitic piezoelectricity ...

Thermal excitation of flexoelectricity in silicon

Flexoelectricity, an electromechanical coupling between strain gradient and polarization, offers a promising dimension to enrich silicon-based devices. Although the flexoelectricity of silicon is known, some fundamental aspects remain ambiguous, such as ...

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

Mathematics
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.

Flexoelectricity in single crystals [PDF]

, 2016
En términos generales, la flexoelectricidad es la respuesta de la polarización a un gradiente de deformación. A diferencia del efecto piezoeléctrico, este efecto está presente en todos los materiales independientemente de su estructura cristalina.

Flexoelectricity versus Electrostatics in Polar Nematic Liquid Crystals [PDF]

Polar nematic liquid crystals have two special features, compared with conventional nematic liquid crystals. First, because of flexoelectricity, the combination of polar order and splay reduces the free energy.
