High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system [PDF]

, 2012
In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedicated to the classical piezoelectric, lead-zirconate-titanate (PZT) ceramic ...

Nanotube Piezoelectricity

, 2003
We combine ab initio, tight-binding methods and analytical theory to study piezoelectric effect of boron nitride nanotubes. We find that piezoelectricity of a heteropolar nanotube depends on its chirality and diameter and can be understood starting from ...

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

AIP 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.

On the coupling effects of piezoelectricity and flexoelectricity in piezoelectric nanostructures [PDF]

AIP Advances, 2017
Flexoelectricity is a novel kind of electromechanical coupling phenomenon that is prevalent in all solid dielectrics and usually of vital importance in nanostructures and soft materials. Although the fundamental theory of flexoelectric solids and related beam or plate theories were extensively studied in recent years, the coupling effect of ...
