Optimum plasmon hybridization at percolation threshold of silver films near metallic surfaces
We experimentally demonstrate the strong interaction and plasmonic by hybridization from a nanosystem having both localized and delocalized surface plasmon modes simultaneously in the presence of a nearby thin continuous metallic film.

| Summary: | We experimentally demonstrate the strong interaction and plasmonic by hybridization from a nanosystem having both localized and delocalized surface plasmon modes simultaneously in the presence of a nearby thin continuous metallic film. In situ dc resistance measurement of silver films and percolation theory were used to accurately determine the systems where the percolation threshold exists by distinguishing the nuclation and growth regions of silver films. We found an optimum plasmon hybridization existing in this percolation threshold region which can be verified from the absorption spectra. We interpret our data in terms of a fitting of the absorption spectra to the Fano-type line shape model. |
