Photoresponsive Piezoelectrics [PDF]

open access: yesFrontiers in Materials, 2021
Most piezoelectric materials are not interactive with visible light, meaning that their band gaps are beyond the photon energies of the visible part of the light spectrum. The first narrow band gap (1.1 eV, the same as silicon) ferroelectric material based on the oxide perovskite structure has been achieved by doping Ni on the B-sites of KNbO3 and ...

Piezoelectric Accelerator [PDF]

open access: yesScientific Reports, 2018
AbstractHere we propose the conception of small-size piezoelectric accelerator of charged particles that operates due to the piezoelectric effect at varying mechanical force applied to piezoelectrics in vacuum. The accelerating voltage and the energy of accelerated particles are estimated.

Measurement of Flexoelectric Effect in Lead Zirconate Titanate Ceramics

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2011
Lead zirconate titanate (PZT) ceramics is usually used as a piezoelectric material. However it has characteristics of not only piezoelectricity but also flexoelectricity.

(K,Na)NbO3-based lead-free ceramics with enhanced temperature-stable piezoelectricity and efficient red luminescence

open access: yesJournal of Advanced Ceramics, 2023
There has been a surge of research interest in the promising lead-free potassium−sodium niobate (KNN)-based ceramics, applications of which could be significantly promoted by improving thermal stability of piezoelectricity.

Piezoelectric mimicry of flexoelectricity [PDF]

open access: yes, 2018
The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectric-like effects with parasitic piezoelectricity ...

Piezoelectricity in nominally centrosymmetric phases

open access: yesPhysical Review Research, 2021
Compound phases often display properties that are symmetry forbidden relative to their nominal, average crystallographic symmetry, even if extrinsic reasons (defects, strain, or imperfections) are not apparent.

Ferroelectricity in glycine: A mini-review

open access: yesFrontiers in Materials, 2022
Glycine is the simplest natural amino acid, a basic building block for various biomaterials. Supramolecular packing of glycine molecules into three main crystalline polymorphs allows controlling their functional properties, such as piezoelectricity and ...
