Fig. 3. DFM-SEM correlative characterization of the plasmonic properties of a tetrameric metamolecule.

Fig. 3

(A) Schematic of the DFM setup for measuring the scattering spectra of a single 80-nm L-AuNP tetrameric metamolecule. (B) Colocalized DFM and SEM images. Scale bars, 1 μm. (C and D) SEM image and scattering spectra (the experimental and theoretic) of the tetrameric metamolecule at different polarization angles of incident light. The orientation angles of the incident light relative to the cluster are shown in the middle column. (E) Theoretic extinction spectrum and surface charge distribution plot of the tetrameric metamolecule when the polarization angle of the incident light was 90°.
