Fabrication and Replication of Arrays of Single- or Multicomponent Nanostructures by Replica Molding and Mechanical Sectioning

he interaction of electromagnetic fields with metallic nanostructures can produce collective oscillations of the conduction electrons at metaldielectric interfaces. These oscilla-tions are known as localized surface plas-mon resonances (LSPRs) and propagating surface plasmon polaritons (SPPs) and are responsible for most of the phenomena in the field of plasmonics.1 Two- and three-dimensional arrays of metallic nanostruc-tures could play key roles in functional ma-terials.
