Description:

The ballistic conductivity and mechanical strength of carbon nanotubes make them ideal for use as wires in nano-scale devices.  Shown here is a self-assembled carbon nanotube network on an array of Si pillars with a 100 nm-diameter and a 300 nm-height fabricated using synchrotron-radiation lithography. The carbon nanotubes were grown using chemical vapor deposition with Fe or Co catalysts.  These nanotubes exhibited floating bridges between pillars when the pillar spacing was comparable with the pillar height. A network-like interconnection was obtained on pillar arrays.  These results demonstrate the possibility of self-assembled wiring of nano-networks.
