The proposed program uses polarization reversal on ferroelectric materials that yield current densities in the ka/cm2 range. The fast change in the polarization vector within the material results in a transition that liberates the polarization induced charges (4 p) resulting in a current pulse limited only by the transition time and space charge effects. The proposed program will develop the technology for microsecond long pulses. The use of ferroelectric material as the a-k structure should control plasma formations that result in gap closure.
