Harmonic demodulation and minimum enhancement factors in field‐enhanced near‐field optical microscopy [PDF]
Journal of Microscopy, 2014 SummaryField‐enhanced scanning optical microscopy relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing the near‐field information recorded in a field‐enhanced scanning optical microscopy experiment, has to surpass the background light ...
