Simple model for the polarization effects in tip-enhanced Raman spectroscopy

Abstract : The paper addresses the polarization properties of tip enhanced Raman spectroscopy TERS through an experimental study on 001 - and 111 -oriented crystalline Si samples and quantitatively describes them by using a simple phenomenological model. The model, conceptually similar to that used in surface-enhanced Raman scattering SERS , is based on the introduction of a phenomenological tip-amplification tensor accounting for the interaction of the tip with the electromagnetic field. It was found to be in a good agreement not only with our experimental data but also with the measurements and numerical simulations of other groups.
