dc.description.abstract
We show how to obtain the symmetry-imposed selection rules for plasmonic
enhancement in surface- (SERS) and tip-enhanced Raman scattering (TERS).
Plasmon-enhanced light scattering is described as a higher-order Raman
process, which introduces a series of Hamiltonians representing the
interaction between light, plasmons, electrons, and phonons. Using group
theory, we derive the active representations for point group symmetries of
exemplary plasmonic nanostructures. The phonon representations that are
enhanced by SERS and TERS are then found as induced representations for the
symmetry group of the molecule or another Raman probe. The selection rules are
discussed for graphene that is coupled to a nanodisk dimer as an example for
SERS and coupled to a tip as a TERS example. The phonon eigenmodes that are
enhanced depend on the symmetry breaking when combining the plasmonic
structures with graphene. We show that the most prominent optical phonon modes
(E2g and A1g) are allowed in all scattering configurations when using a
nanodimer as a plasmonic hotspot. We predict the activation of the silent B2g
as well as infrared-active A2u and E1u modes in SERS for crossed
configurations of the incoming and scattered light. There is a systematic
difference between spatially coherent and incoherent plasmon-enhanced Raman
scattering, which is responsible for a dependence of TERS on the phonon
coherence length.
