Figure 2

SEM images of the Si nanostructures and measured hemispherical reflectance spectra. (a) 45° tilted- and (b) cross-sectional-view SEM images of the Si nanostructures fabricated using different HNO3 concentrations from 10% to 22% in an aqueous solution. (c) Measured hemispherical reflectance spectra of the corresponding Si nanostructures as a function of wavelength.
