Figure 2

Reflectance and transmittance spectra: (a) the reflectance of double-side polished c-Si substrate (black curve) and a sample of SiNWs ( L  = 2.6 μm), with and without Ag nanoparticles (blue and red curves, respectively), and the first derivative of the reflectance of the sample of SiNWs without Ag nanoparticles in the inset; (b) the transmittance of double side polished c-Si substrate (black curve) and a sample of SiNWs ( L  = 2.6 μm) with and without Ag nanoparticles (blue and red curves, respectively).
