The Regulation of Surface-Enhanced Raman Scattering Sensitivity of Silver Nanorods by Silicon Sections
Figure 2
Oblique-view SEM images of vertically aligned nanorods consisted of four silver sections with length of 25 nm and silicon sections with length of (a) 10 nm, (b) 20 nm, (c) 40 nm, and (d) 60 nm, respectively.
