Nanostructure design for surface-enhanced Raman spectroscopy – prospects and limits [PDF]

Journal of the European Optical Society-Rapid Publications, 2008
Surface-enhanced Raman spectroscopy (SERS) allows single-molecule detection due to the strong field localization occurring at sharp bends or kinks of the metal-vacuum interface. An important question concerns the limits of the signal enhancement that can
