Paper Abstract

We use a laser-irradiated metal tip to create a locally enhanced field at the tip apex. The tip acts as an optical antenna and is held a few nanometers above the sample surface so that a highly localized interaction between the enhanced field and the sample is achieved. The method has been successfully combined with vibrational spectroscopy by making use of the well-known effect of surface enhanced Raman scattering (SERS). We mapped out the vibrational modes of individual single-walled carbon nanotubes (SWNT) with a resolution down to l0nm.
