This paper reports on a novel and versatile method to synthesize sharp-edged
crescent-shaped half-nanotubes (HNTs) using a flexible template-based nanofabrication method
assisted by atomic layer deposition. This was achieved by electrodeposition inside crescent-shaped
nanochannels created by a controlled removal of a sacrificial layer, which was deposited by atomic
layer deposition onto the pore walls of an anodic aluminum oxide template. This method provides a
high degree of freedom in the manipulation of the morphological properties of HNTs such as the
edge sharpness, opening, gap size, and the wall thickness. Initial optical investigations of the HNTs
reveal distinct surface plasmon resonance by dark field scattering spectra and surface enhanced
Raman spectrum. |
