Nonzero Waveveector Graphene Excitation Localized Surface Plasmons


Abstract image

Single layer graphene measurements of the enhanced Raman distribution of the electric chemical surface give unique information about the resonant excitation induced by localized surface plasmons under controlled electron or hole doping. Highly charged electromagnetic fields from the LSPs of graphene-free Au nanodimer structures can produce holes and electrons of electrochemical potential beyond the limit of far-level light illumination. The electrochemical situational SERS spectra enhance the excitation of non-zero waves by observing normally prohibited Raman bands in graphene. The present findings point to a new approach to breaking the limit of graphene and other optoelectronic interactions and other photochemical reactions.
