Abstract

A periodic dependence on the Au segment length is observed for the electric field at the nanogap of long-segment Au nanostructures. An optimized geometry of these platforms leads to an intense surface-enhanced Raman scattering (SERS) signal at the nanogap (see picture). Information about molecular transport and vibrational spectra may therefore be simultaneously obtained.
