Polarization-Selective Imaging of the Enhanced Local Field at Gold Nanoparticle Junctions

다국어 초록 (Multilingual Abstract)

The electromagnetic gap-mode is believed to be the major cause of
the colossal surface-enhanced Raman scattering (SERS) signals
recently discovered. However, no direct spatial correlation among
the local field and the morphology has been established thus far.
Here, we demonstrate that scattering-type apertureless near-field
scanning optical microscopy (ANSOM) can visualize the gap-mode
formed between gold nanoparticles with a spatial resolution better
than 10 nm.
