The nETR spectra for different V-shaped nanorod structures. (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 different corner parts for g = 10 nm and <a onClick="popup('http://www.nanoscalereslett.com/content/8/1/209/mathml/M4','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/8/1/209/mathml/M4">View MathML</a>.
