The quest for enhancing light-matter interactions at the nanoscale has led scientists to nanophotonic systems that support the smallest possible modes, which are currently realized via particle-on-mirror (PoM) geometries using plasmonic particles. Th

Single-molecule surface-enhanced Raman scattering (SM-SERS) is one of the vital applications of plasmonic nanoparticles. The SM-SERS sensitivity critically depends on plasmonic hot-spots created at the vicinity of such nanoparticles. In conventional
