Abstract :
In this paper, we present the grow of mm-long, well-aligned individual single wall carbon nanotubes (SWNTs) on flat substrates suitable for device fabrication. We also demonstrate the feasibility of using such long nanotubes as nanoscale antennas. To fabricate such antenna structure, well separated and well aligned individual nanotubes were grown by adopting a newly developed method to pattern catalyst islands with uniform size catalyst nanoparticles. The length of nanotubes can be precisely controlled by chemical etching using oxygen plasma treatment at desired locations. Dipoles were fabricated on individual long nanotubes using photolithography method.
