Perspective—Quasi-Babinet Complementary Plasmonic Templates: A Platform to Perform Spectroelectrochemistry

Plasmonic bilayers fabricated by depositing metal on nanopillar or nanocavity arrays are an effective solution for the industrial scale production of plasmonic templates. Such structures commonly consist of a disk array and a quasi-Babinet complementary perforated film comprised of holes, which are displaced vertically by the pillar or cavity.
