Abstract
In surface-enhanced Raman scattering (SERS), the giant field enhancements generated by plasmonic nanostructures compensate for the relatively weak Raman scattering cross sections of many molecules. The effect is so substantial that Raman spectroscopy can be performed on single molecules (e.g., [1]). A structure that has proven especially effective for SERS is the dimer nanoantenna, i.e., two metal nanoparticles separated by a small gap.
