The nETR spectra for different V-shaped nanorods structures, withθ1=θ2= 60°,θD= 60°, andθA= 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 . The other parameters are L′ = 290 nm and d = 20 nm.
