Behavior of Charged Dislocations in Ionic Crystals with an Electric Field Applied. II

Abstract

The response to an applied electric field of charged edge dislocation and surrounding charge cloud system is calculated for the case that the cloud is composed of two species of movable charged point defects. It is shown that at low frequency region the charged dislocation senses the unscreened field and the coefficient of the converse piezo-electric effect does not coincide with that of the direct effect.
