In addition, we recently developed another novel plasmonic material, based on Plasma Enhanced Atomic Layer Deposition (PEALD) of Ag, which results in strong plasmonic properties of flat Ag films. It will be shown as-deposited flat PEALD Ag films exhibit unexpected plasmonic properties and the plasmonic enhancement can differ significantly, depending on the microstructure of the Ag film. Electric field simulations suggest that the plasmonic behavior is due to air gaps that are an inherent property of the PEALD growth of Ag and account for the trends observed in SERS. This unusual plasmonic behavior is very similar to what would be expected in hybrid spoof plasmonics and suggests that PEALD Ag is a metamaterial.
