Modeling and parametric analysis of a piezoelectric flexoelectric nanoactuator

open access: yesMATEC Web of Conferences, 2016
With the development of nanotechnology, nanoactuators have recently re-stimulated a surge of scientific interests in research communities. One of the interesting transduction mechanisms that showed high efficiency at the nanoscale was flexoelectricity ...

Self-powered tunable photodetection via flexoelectric engineering of single-phase 2HMoS2

open access: yesJournal of Materiomics
Two-dimensional (2D) molybdenum disulfide (MoS2) has shown considerable potential for photodetection, yet existing MoS2-based photodetectors require either external voltage bias or complex heterojunctions.

Flexoelectric and dielectric phenomena in helicoidal liquid crystals [PDF]

open access: yes, 2013
The unique features of flexoelectric and dielectric effects are investigated, and exploited for a variety of functions, in a wide range of helicoidal liquid crystal systems, including non-chiral, cholesteric and blue phases.

Flexoelectric Instability in Bent-Core Nematic Liquid Crystals

open access: yesCrystals
We develop a theoretical model for the flexoelectric instability in bent-core nematic liquid crystals, focusing on the coupling between elastic distortions and an external electric field through flexoelectric polarization.

Size-dependent electromechanical properties in piezoelectric superlattices due to flexoelectric effect

open access: yesTheoretical and Applied Mechanics Letters, 2017
Piezoelectric superlattice is a potential component for nanoelectromechanical systems. Due to the strong nonlocal effect such as flexoelectric effect at interfaces, classical piezoelectric theory is unable to accurately describe the electromechanical ...

Demo 24-04 Microwave Polarization

open access: yes, 2001
This demonstration illustrates one mechanism for the polarization of electromagnetic waves, using the apparatus as shown in Figure 1. The result is counterintuitive in that the waves that pass through the polarizer are polarized perpendicular to the ...

Demo 24-06 Polarization by Double Reflection

open access: yes, 2001
Polarization of light is obtained by using two reflections from dielectric plates, as in Figure 1. This demonstration illustrates the effect of double reflection on the polarization of an initially unpolarized light beam.

Upper bounds for flexoelectric coefficients in ferroelectrics [PDF]

open access: yes
Flexoelectric effect is the response of electric polarization to the mechanical strain gradient. At the nano-scale, where large strain gradients are expected, the flexoelectric effect becomes appreciable and may substitute piezoelectric effect in ...
