The nETR spectra for different V-shaped nanorods structures, with θ ₁ = θ ₂ = 60°, θ _D = 60°, and θ _A = 30°. (a) The nETR spectra for V-shaped structures shown in Figure 3a with different gap widths compared with the single nanorod structure. (b) The nETR spectra for V-shaped structures with a sharp corner part (black), cylinder corner part (red), or no corner part (green), g = 10 nm, and $r_0=20\sqrt{3}\mathrm{nm}$. The other parameters are L′ = 290 nm and d = 20 nm.
