Plasmonic coupling of SiO₂-Ag "post-cap" nanostructures and silver film for surface-enhanced Raman scattering

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

We demonstrate a surface-enhanced Raman scattering (SERS) substrate consisting of SiO₂-Ag "post-cap" nanostructures with an underlying silver film. Optimized coupling between free-standing Ag caps and the underlying silver film results in a maximum enhancement factor of 2.38×10⁹.
