Flexoelectric Thin-Film Photodetectors

Nano Letters, 2021
The flexoelectric effect, which manifests itself as a strain-gradient-induced electrical polarization, has triggered great interest due to its ubiquitous existence in crystalline materials without the limitation of lattice symmetry. Here, we propose a flexoelectric photodetector based on a thin-film heterostructure.

When Flexoelectricity Drives Triboelectricity

Nano Letters, 2022
Triboelectricity has been known since antiquity, but the fundamental science underlying this phenomenon lacks consensus. We present a flexoelectric model for triboelectricity where contact deformation induced band bending at the nanoscale is the driving force for charge transfer.

Flexoelectricity in metals

Journal of Applied Physics, 2021
Flexoelectricity is an electromechanical phenomenon that, unlike piezoelectricity, is present in any material. While the largest flexoelectric response is observed in ferroelectrics and related materials, its manifestations in various other materials are of great interest for a broad scope of scientific and industrial tasks.

Nanoscale Flexoelectricity

Advanced Materials, 2013
AbstractElectromechanical effects are ubiquitous in biological and materials systems. Understanding the fundamentals of these coupling phenomena is critical to devising next‐generation electromechanical transducers. Piezoelectricity has been studied in detail, in both the bulk and at mesoscopic scales.

Flexoelectric spectroscopy

Journal of Physics: Condensed Matter, 2013
Flexoelectricity is an increasingly popular subject because it can be extremely large in thin films and permits switching of devices in nonpolar (non-piezoelectric) crystals via application of inhomogeneous stresses. However, recent work has been limited to macroscopic measurement of voltage or strain.

Flexoelectricity in Electroconvection

Molecular Crystals and Liquid Crystals, 2009
We reexamine the influence of the flexoelectricity on the electroconvection (EC), the effect which has previously been studied in the conductive EC regime only. Now we extend our studies to the dielectric EC, and to the parameter range for which the standard model of EC excludes the existence of the instability.

Surface polarization and flexoelectric effect

Journal of Applied Physics, 1991
In order to evaluate the order of magnitude and to establish the origin of the surface polarization, experimental investigations of direct piezoelectrical effect in nematic liquid crystals have been performed. The experimental setup used allows the temperature dependence of the electrical response of a nematic sample, submitted to periodic acoustic ...
