Aluminum nanoparticle deposition for scalable plasmonic metasurface fabrication

Abstract

Large-area plasmonic metasurfaces have attracted interest as potential tools for a wide range of applications, from colorchanging glass to improved efficiency of solar cells. These potential applications necessitate the capability to fabricate such surfaces at scale. One potential approach to resolve this issue is to use nanoimprint lithography to mold a metasurface structure and then use chemically synthesized nanoparticles as the metallic elements. By combining aluminum nanoparticles with electrophoretic deposition, a low-cost method of scalable fabrication could be achieved.
