摘要： A method is provided for improving metallic nanostructure stability. The method provides a substrate, and using a physical vapor deposition (PVD) process for example, deposits metallic nanostructures having a first diameter overlying the substrate. Some examples of metallic nanostructures include Ag, Au, and Al. The metallic nanostructures are annealed in an atmosphere including an inert gas and H2. The annealing temperature is less than the melting temperature the metal material in bulk form. In response to the annealing, stabilized metallic nanostructures are formed. If the stabilized metallic nanostructures are exposed to an ambient air environment the stabilized metallic nanostructure maintain the first diameter. Typically, the metallic nanostructures are initially formed having a rectangular shape with corners. After annealing, the stabilized metallic nanostructures have a dome shape.

摘要： An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.
