Pairs of nanoparticles separated by a controllable gap size that can be as small as 3 nm are fabricated via a top‐down lithographic procedure. This fabrication method would be useful not only for surface‐enhanced Raman scattering, where it could potentially enable single‐molecule sensitivity, but also for other applications in plasmonics and nonlinear optics.
