ABSTRACT:
A method for forming inverted ferroelectric domain regions in a substrate including ferroelectric material and having two major opposite surfaces. The method includes application of controlled electric field in selected regions to inhibit subsequent nucleation and growth of selected domains; applying a conductive electrode over the opposite major surfaces; and providing a voltage to the conductive electrodes having a sufficient magnitude and duration to cause the ferroelectric polarization to invert in selected unmodified regions.
