TERS Principle

Tip-Enhanced Raman Spectrosocpy (TERS)

To obtain a spectral signature at a finer scale than the micrometer (currently in the order of a few nanometers), the source of the Raman excitation must itself be nanometric. This recent methodology exploits the amplification of the electromagnetic field and therefore of the Raman signal observed at nano-antennas (by peak effect), it is the TERS effect. This new methodology, first proposed in the 2000s, is difficult to implement and remains the preserve of a few specialized laboratories.

La spectroscopie Raman exaltée de pointe (TERS)

Pour obtenir une signature spectrale à une échelle plus fine que le micromètre (de l'ordre de quelques nanomètres à l'heure actuelle), il faut que la source de l'excitation Raman soit elle-même nanométrique. Cette méthodologie récente exploite l'amplification du champ électromagnétique et donc du signal Raman observée au niveau de nanoantennes (par effet de pointe), c’est l’effet TERS.
