Prototype of Illumination-Collection Mode Scanning Near-Field Optical Microscopy and Raman Spectroscopy with Gold Inner-Coated Aperture-Less Pyramidal Probe

We have prototyped illumination-collection mode scanning near-field optical microscopy (SNOM) and near-field Raman spectroscopy (NFRS) with gold inner-covered aperture-less pyramidal probe in order to study the possibility to detect optical images, and Raman spectrum and Raman peak shift for stress distribution in Si device with high resolution of about 10 nm.
