Abstract

A plasmonic display device is provided that uses physical modulation mechanisms. The device is made from an electrically conductive bottom electrode and a first dielectric layer overlying the bottom electrode. The first dielectric layer is a piezoelectric material having an index of expansion responsive to an electric field. An electrically conductive top electrode overlies the first dielectric layer. A first plasmonic layer, including a plurality of discrete plasmonic particles, is interposed between the top and bottom electrodes and in contact with the first dielectric layer. In one aspect, the plasmonic particles are an expandable polymer material covered with a metal coating having a size responsive to an electric field.
