On the coupling effects of piezoelectricity and flexoelectricity in piezoelectric nanostructures

open access: yesAIP 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

Importance of second-order piezoelectric effects in zincblende semiconductors

open access: yes, 2006
We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has strong contributions from second-order effects that have been neglected so far.

Extending device performance in photonic devices using piezoelectric properties [PDF]

open access: yes, 2013
This study focuses on the influence of epi-layer strain and piezoelectric effects in asymmetric GaInAs/GaAlAs action regions that potentially lead to intra-cavity frequency mixing. The theoretical limits for conduction and valence band offsets in lattice-
