Transversal flexoelectric coefficient for nanostructures at finite deformations from first principles [PDF]

, 2021
We present a novel formulation for calculating the transversal flexoelectric coefficient of nanostructures at finite deformations from first principles. Specifically, we introduce the concept of radial polarization to make the coefficient a well-defined ...

Effect of normal vibration on the dynamic flexoelectric response of a thin dielectric plate with symmetrical electrode thickness

Alexandria Engineering Journal
In this paper, we investigate the effect of thickness-normal vibration on the dynamical flexoelectric effect induced in a thin dielectric plate covered by two electrodes with either equal or unequal thicknesses.

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...
