TERS
TERS — Raman Spectroscopy with the enhancement of the tip. Measurements based on AFM microscopy. Mode TERS Raman spectrum is enhanced when a sharp tip with a gold coating approaches the illuminated sample surface. Using the cantilever of an AFM as an amplifier, measure the chemical properties of the sample in the nano-range by using the built-in Raman spectrometer, simultaneously obtaining topographic data by using ASM.
