  • Patent number: 11119046
    Abstract: A substrate formed by using a sliding dielectric film with a low surface energy that activates surface migration of metal adatoms and a method of manufacturing the same. More particularly, a substrate with a sliding dielectric film includes a substrate; a sliding dielectric film with a low surface energy formed on the substrate; and a nanoparticle formed on the sliding dielectric film, wherein the surface energy of the nanoparticle is at least 1000 mJ/m2 greater than the surface energy of the sliding dielectric film. The substrate has a very high SERS enhancement factor with low light loss characteristics in the entire visible region by maximizing the plasmonic coupling between highly-dense and spaced-apart nanoparticles and between the lower substrate and the upper nanoparticles.
