Abstract
The present invention generally relates to circuits on the nanotechnology scale. Specifically, it is directed to methods of fabricating carbon nanotube-based (i.e., CNT-based) circuits. The method involves providing a mixture of carbon nanotubes that is substantially disaggregated and patterning carbon nanotubes through the use of electrostatic forces. Carbon nanotubes in the mixture are typically disaggregated through the introduction of positive charge on the individual nanotubes. The patterning of the carbon nanotubes is typically accomplished using electrostatic attraction between pre-formed metal lines and the charged carbon nanotubes.
