Abstract

original image

On page 4268, Seung-Man Yang and co-workers report the fabrication of unprecedentedly coordinated Au-capped elliptical silicon nanowire arrays for sensing applications using prism holographic lithography. Depending on the vertical gap distance, which is a function of the catalytic wet etching time, the resulting hybrid structures exhibit tunable optical properties. Furthermore, highly enhanced surfaceenhanced Raman scattering (SERS) and fluorescence signals can be derived from the structural effects with large-scale sample homogeneity.
