Ferroelectric domain walls separate regions of material with different electric polarization orientations, and their physical properties can be completely different from the surrounding bulk material.
This is the reason for the increment of the electric polarization of the stabilized CPVC sample.
With his colleagues at University of Michigan and collaborators from Cornell University, Penn State University, and University of Wisconsin, Madison, Xiaoqing Pan, a professor in the U-M Department of Materials Science and Engineering, has designed a material system that spontaneously forms small nano-size spirals of the electric polarization at controllable intervals, which could provide natural budding sites for the polarization switching and thus reduce the power needed to flip each bit.
The piezoelectric effect occurs in materials where an externally applied elastic strain causes a change in electric polarization producing a charge and a voltage across the material.
An electret in contrast to the field of a magnetic body is a solid die electric processing, long term electric polarization, forming an electric field in the environment.
The electric polarization of the ferroelectric crystals is shifted between two stable states by the application of an electric field.
An application of a large electric field to the material will cause the spontaneous electric polarization of the ferroelectric phases to orientate so as to oppose the direction of the electric field lines.
