(a) The sketch of the NCND structure and the incident light (, , , , , and ). (b) The LFE spectra of the nanocrescent and the NCND structure.
LFE factors of the quadrupole resonance peaks in the NCND structures as a function of the nanogap widths (a) and the tip-to-tip distances (b).
The distribution of the electric field amplitude of quadrupole resonance modes of (a) nanocrescent, (b) nanogap, and the NCND structures with nanogap widths of 10 (c) and 4 nm (d).
LFE factors of the NCND structures as a function of the overall sizes. For the scale factor of 1, 1/2, and 1/4, the tip-to-tip distances are 30 nm, 20 nm, and 15 nm, respectively.
