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

Theoretical 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 ...

Dynamic flexoelectric effect in perovskites from first-principles calculations

Using the dynamical matrix of a crystal obtained from ab initio calculations, we have evaluated the strength of the dynamic flexoelectric effect and found it comparable to that of the static bulk flexoelectric effect, in agreement with earlier order-of ...

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.

Effect of annealing on flexoelectricity in hafnium oxide (HfO2)

Applied Physics Letters
Flexoelectricity is universal in all dielectrics, effective at high temperatures, and a promising transduction technique for nanoelectromechanical systems (NEMS). However, as flexoelectricity is still in its early stages, many aspects require further investigation.

Dielectric Behavior of Antiferroelectric Liquid Crystals in Presence of Flexoelectric Effect

, 2017
We studied theoretically the effect of flexoelectricity on the behavior of dielectric fluctuations of antiferroelectric liquid crystals (AFLCs) influenced by the mechanical distortion associated with flexoelectric effect.

Flexoelectric effect in the reversal of self-polarization and associated changes in the electronic functional properties of bifeo3 thin films

, 2018
Flexoelectricity can play an important role in the reversal of the self-polarization direction in epitaxial BiFeO3 thin films. The flexoelectric and interfacial effects compete with each other to determine the self-polarization state.
