Optical characteristics of nanospace of silver nanowire on a silver mirror

摘要

Localized surface plasmons in subnanometer gaps defined by metal nanoparticle dimer has recently attracted attention as a high-sensitivity sensor with a small volume. We demonstrated multiple gap plasmons by a single silver nanowire with a spacer layer on silver film, that is, nanowire on mirror (NWoM) in the dark-field with polarization-dependent.
