Similarly, ferroelectric materials have a spontaneous electric polarization, the direction of which can be switched with an applied electric field.
The material and the thickness of ferroelectric film are selected such that the product of the relative dielectric constant of ferroelectric film and the electric field across ferroelectric film is less than 15.6 Mv/cm.
When the device is used as a sonic actuator, the first and second electrode patterns are configured to introduce an electric field into the ferroelectric material when voltage is applied to the electrode patterns.
You can polarize a ferroelectric crystal by heating it, placing it in a vertically oriented electric field, and then cooling it.
In another feat of memory, researchers reported two years ago that a light-induced electric field could imprint a new refractive index along one dimension of a ferroelectric crystal.
