Abstract

Optimization of plasmonic disc on pillar (DOP) structures guided by FDTD simulations, their deterministic fabrication and characterization by both Raman microscopy and dark-field spectroscopy are discussed. SERS enhancement factors exceeding 109 are achieved using optimized DOP structures.
