| Metallic and semiconductor nanoparticles and nanorods promise to play a critical role in the drive for miniaturization of optoelectronic devices. We investigate the possibility to make metallic and semiconductor nanorod arrays using a new type of amphiphilic templates. The template structure is based on the epitaxial organization of alkane derivatives on the graphite lattice. We report the fabrication of arachidic acid monolayer template by spin coating. AFM shows that arachidic acid forms ordered stripes with periodicity equaling its bilayer thickness. The metal ion arachidate film is reacted with hydrogen sulfide in order to produce sulfide nanorods. The copper arachidate film shows curved stripes due to dimer formation, which become straight after reacting with hydrogen sulfide. Removal of the organic template by a solvent reveals the formation of sulfide nanorods. The new template may facilitate the fabrication of nano-arrays of different materials. |
