Enhancement Factor of TERS Tips: An Imaging and a Spectroscopic Approach

The enhancement factor in tip-enhanced Raman spectroscopy (TERS) is a complex parameter to measure. It depends on the measurement condition of the instrument, sample properties as well as the TERS tip characteristics.

Therefore, variation of the enhancement factor reported in TERS literature ranges from 30 to an astounding value of 1013.
