Figure 2

Schematic illustration of the light path in the Si NWA with a difference of the substrate, (a) Ag substrate and (b) PA substrates. (c) Measured reflectance spectra of the Si NWAs with a diameter ranging from 80 to 170 nm on (left) Ag and (right) PA substrates. (d) Photographs of the Si NWAs on Ag and PA substrates. (e) 3D HSV (e.g., Hue, Saturation, and Value) of Si NWAs on Ag and PA substrates. (f) The top view of (e) with a color map. (g) The Value information of the Si NWA as a function of the diameter on different substrates. The bare Ag and PA have the Values of 94% and 20%, respectively.
