研究目的
Investigating strong exciton-plasmon coupling and plasmon-mediated hybridization between the Frenkel (F) and Wannier–Mott (WM) excitons of an organic-inorganic hybrid system consisting of a silver ring separated from a monolayer WS2 by J-aggregates.
研究成果
The study demonstrates strong exciton-plasmon coupling between the F exciton of organic J-aggregates and the WM exciton of inorganic WS2 through their mutual interaction with a plasmonic nanocavity. The large electric field enhancements and maximizing overlap between the plasmonic field mode and the exciton states result in three plexciton branches in the extinction spectra. The strong couplings among F excitons, WM excitons, and LSPRs can be modulated by tuning the temperature or the oscillator strength of J-aggregates, offering potential applications in inversionless lasing, superfluidity, and topologically non-trivial states.
研究不足
The study focuses on theoretical simulations and modeling, which may not fully capture all experimental conditions and variations. The damping losses are not fully accounted for in the coupled oscillator model, which could affect the accuracy of the fitting results.
