Figure 5

(a) Transmittance spectra of an ~5-nm -thick Au membrane: experimental result (black line) and theoretical simulation result (red line). The inset is an optical image of Au membrane on glass substrate. The two circles are marked to indicate the position of light spot on Au membrane and on glass substrate as background, respectively. (b) I–V curve of an ~5-nm-thick Au membrane spanning two gold electrodes with a distance of 10 μm. The inset is the optical image of the device (scale bar, 10 μm). The thickness of the Au membranes was confirmed by AFM measurement.
