Abstract

In this paper, a unique nanoscrew Si structure is presented. The nanoscrew surface is made by anodized aluminum oxide (AAO) mask formation followed by extended deep reactive ionic etching (DRIE). Dense random zig-zag pillar structures that represent screw shapes are formed, with 1 um in height and the bottom base width ranging from 100 nm to 250 nm. The tip of the nanoscrews have radius of curvature even lower than 10 nm. The apparent naked-eye view of the nanoscrew surface, which only consists of nanopatterned N-type single crystalline Si is diffusively green. The optical properties of nanoscrew Si with and without metal deposition is presented as discussion in applications for SERS.
