On the extrinsic piezoelectricity [PDF]

Ferroelectrics, 2000
This work presents a continuation of our last paper, concerning the theory of the response of an antiparallel domain structure in a plate-like electroded sample to external electric field. The theory is based on the exact formula for free energy of the system, formed of a central ferroelectric part, isolated from electrodes (with a defined potential ...

Piezoelectric Accelerator [PDF]

Scientific 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.

Piezoelectricity in perovskite-type pseudo-cubic ferroelectrics by partial ordering of off-centered cations

Communications Materials, 2020
Strong piezoelectricity is typically due to reorientation of ferroelectric domains and is not expected in cubic systems. Here, the strong piezoelectricity of pseudo-cubic 0.3BaTiO3–0.1Bi(Mg1/2Ti1/2)O3–0.6BiFeO3 is explained in terms of partial ordering ...
