Introduction to piezoelectricity and electrospun piezoelectric materials and devices [PDF]

open access: yes, 2019
Piezoelectric materials are increasingly being used in a wide range of applications. Single crystals, ceramics and polymers are all being used sensors, actuators and energyharvesting applications. Among the most used piezoelectric materials are lead zirconate titanate (PZT) and barium titanate (BaTiO3) ceramics and the polymer poly(vinylidene fluoride)

Electromagnetic Response of Layered Superconductors with Broken Lattice Inversion Symmetry [PDF]

open access: yes, 2004
We investigate the macroscopic effects of charge density waves (CDW) and superconductivity in layered superconducting systems with broken lattice inversion symmetry (allowing for piezoelectricity) such as two dimensional (2D) transition metal ...

Piezoelectricity of Cholesteric Elastomers

open access: yes, 1994
We consider theoretically the properties of piezoelectricity in cholesteric elastomers. We deduce using symmetry considerations the piezoelectric contributions to the free energy in the context of a coarse-grained description of the material. In contrast

Strong enhancement of piezoelectric constants in ScxAl1−xN: First-principles calculations

open access: yesAIP Advances, 2016
We theoretically investigate the piezoelectricity of ScxAl1−xN in the entire range of x by first-principles calculations. We find that the piezoelectric constants of wurtzite-type ScxAl1−xN significantly enhance as x increases from 0 to 0.75.

Origin of giant negative piezoelectricity in a layered van der Waals ferroelectric

open access: yesScience Advances, 2019
Lattice topology and anisotropic chemical bonds underpin unusual negative longitudinal piezoelectricity in van der Waals solids. Recent research on piezoelectric materials is predominantly devoted to enhancing the piezoelectric coefficient, but overlooks

Modeling electromechanical properties of layered electrets: Application of the finite-element method

open access: yes, 2004
We present calculations on the deformation of two- and three-layer electret systems. The electrical field is coupled with the stress-strain equations by means of the Maxwell stress tensor.
