Molecular shape and flexoelectricity [PDF]
Liquid Crystals, 2000 We performed Monte Carlo simulations of systems of wedge-shaped objects formed from Gay-Berne ellipsoids joined to Lennard-Jones spheres. We studied two different wedge shapes, one more asymmetric than the other. The bend and splay flexoelectric coefficients were measured in the isotropic and smectic phases using linear response theory, and found to be

Photoresponsive Rotaxanes Switch Lipid Bilayer Neuromorphic Behavior with Light
Advanced Electronic Materials, EarlyView.A rotaxane consisting of a macrocycle ring with two azobenzene units mechanically interlocked onto an amphiphilic axle was incorporated into droplet interface bilayers (DIBs). Photoswitching between the azobenzene configurations on the ring resulted in cycling between memristive and memcapacitive behaviors in lipid bilayers, enabling programmable ...

On the coupling effects of piezoelectricity and flexoelectricity in piezoelectric nanostructures
AIP Advances, 2017 Flexoelectricity is a novel kind of electromechanical coupling phenomenon that is prevalent in all solid dielectrics and usually of vital importance in nanostructures and soft materials. Although the fundamental theory of flexoelectric solids and related

Giant Flexoelectric Effect in Ferroelectric Epitaxial Thin Films
, 2011 We report on nanoscale strain gradients in ferroelectric HoMnO3 epitaxial thin films, resulting in a giant flexoelectric effect. Using grazing-incidence in-plane X-ray diffraction, we measured strain gradients in the films, which were 6 or 7 orders of ...
