Near-Field Photochemical Imaging of Noble Metal Nanostructures
Christophe Hubert,Anna Rumyantseva,Gilles Lerondel,Johan Grand,Sergei Kostcheev,L. Billot,Alexandre Vial,Renaud Bachelot,Pascal Royer,Shih-Hui Chang,Stephen K. Gray,Gary P. Wiederrecht,George C. Schatz +12 more
TL;DR: The sub-diffraction imaging of the optical near-field in nanostructures, based on a photochemical technique, is reported, which is a first step toward additional methods for resolving confined optical near fields, which can augment scanning probe methodologies for high spatial resolution of opticalnear fields.

Production of gold tips for tip-enhanced near-field optical microscopy and spectroscopy: analysis of the etching parameters
TL;DR: In this paper, the etching parameters that are used for manufacturing gold tips for tip-enhanced near-field optical microscopy and spectroscopy were analyzed in detail and a set of parameters allowing reproducible production of gold tips with 20nm radius of curvature was proposed.

Light depolarization induced by sharp metallic tips and effects on Tip-Enhanced Raman Spectroscopy
TL;DR: In this paper, the authors describe the state-of-the-art experimental techniques, focusing the attention on the strategies to reduce the far-field background, on new processes to fabricate sharp metallic tips and on the effect of the depolarization produced by metallic tips on the tip-Enhanced Raman spectra of bulk crystals.
