Abstract
A linearized ferroelectric capacitor includes a ferroelectric dielectric medium; a doped region in the ferroelectric dielectric medium, the doped region having a charge of a first polarity which divides the medium into two sections of opposing polarized domains; and a pair of electrodes on the ferroelectric medium having a contact potential of a second, opposite polarity to that of the doped region for reinforcing and stabilizing the polarized domains in each section.
