1. A method for generating a domain patterned ferroelectric structure comprising:

  • a. depositing a conductive layer on a top surface of a ferroelectric material and a bottom surface of a ferroelectric material, the top surface and the bottom surface of the ferroelectric material corresponding to surfaces substantially normal to the z-polarization vectors of the ferroelectric material;

    b. applying a sufficient bias voltage across the conductive layer on the top surface and the conductive layer on the bottom surface to pole the z-polarization vectors into a first orientation; and

    c. applying a sufficient bias voltage to selected portions of the conductive layer on the top surface on the ferroelectric material and the conductive layer on the bottom surface of the ferroelectric material to orient corresponding portions of the z-polarization vectors to a second orientation.
