Morphology and optical features of bare SiNWs. (a) SEM image of bare SiNWs (BS, 6 μm-long) on a Si substrate. (b) TEM image of a top-end region (<1 μm) of Au NP-coated SiNWs (AS). (c) Histogram of the Au NP diameters in the AS arrays. (Insets show the illustration and optical photographs of BS and AS embedded in PDMS). The experimental optical spectra of BS (black) and AS (red) embedded in PDMS: (d) transmittance, (e) reflectance, and (f) absorptance. Dotted lines shown in panels d-f correspond to calculation results of a 6-μm-thick Si film.
