Resolution: standard / high Figure 4.
Infrared photoluminescence and Raman spectra: (a) the PL and Raman spectra 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 inset shows the Raman peak after subtraction of the PL background; (b) Raman
spectra the samples of SiNWs with two different thicknesses, and the inset shows dependence
of the Raman intensity on the length of SiNWs (dashed red curve corresponds to a fit
by the logarithmic function).
