Piezoelectric effects in electroreflectance
Solid State Communications, 1970Abstract The contribution of piezoelectric strain to electroreflectance is investigated. The symmetry properties of this contribution are deduced for zincblende materials, and contrasted with those of electroreflectance. Separate observations of these contributions is shown to be possible, and good agreement with the phenomenological, tensorial ...

Effective charges and piezoelectricity
Physical Review B, 1974The effective charge for piezoelectricity is calculated using the bond-orbital model and Martin's internal-displacement parameters. Direct and simple calculations made with no additional parameters lead to a semiquantitative description of this effect.

The piezoelectric effect in polymers
Polymer Mechanics, 1972A series of polymers with varying polarity and chain rigidity has been investigated. On the basis of the results obtained it is concluded that piezoelectric properties are to be found in polarized polymers with small dipole groups and a rigid chain due to their polarity.

Journal of Applied Physics, 2011
In this work, using a combination of a theoretical framework and atomistic calculations, we highlight the concept of “surface piezoelectricity,” which can be used to interpret the piezoelectricity of nanostructures. Focusing on three specific material systems (ZnO, SrTiO3, and BaTiO3), we discuss the renormalization of apparent piezoelectric behavior ...

On the Piezoelectric Effect of Bone
Journal of the Physical Society of Japan, 1957The piezoelectric effect of bone has been observed similarly to the case of wood or ramie. The specimens were cut out from the femur of man and ox, and dried completely by heating. The piezoelectric constants were measured by three different experiments, that is, measurements of the static direct effect, the dynamic direct effect and the dynamic ...

Chiral effects in piezoelectricity
Mechanics Research Communications, 2017Abstract This paper is concerned with the linear theory of piezoelectricity for Cosserat continua. The deformation of homogeneous and isotropic chiral materials is investigated. First, a counterpart of the Boussinesq–Somigliana–Galerkin solution in the classical elastostatics is presented.
