Methods of Forming Carbon Nanotubes

A method of forming carbon nanotubes, comprising:

• forming an electrically conductive layer on a substrate;
• forming a catalytic metal layer on a sidewall of the electrically conductive layer;
• growing a plurality of carbon nanotubes from the catalytic metal layer;
• and
• exposing the plurality of carbon nanotubes to an organic solvent while concurrently applying a centrifugal force to the plurality of carbon nanotubes.

A method of forming a carbon nanotube (CNT), comprising:

• forming an insulation layer on a substrate;
• forming a metal structure on the insulation layer;
• forming a catalyst spacer on a sidewall of the metal structure;
• growing a plurality of CNTs from a lateral surface of the catalyst spacer;
• rotating the substrate having the CNTs thereover;
• and
• providing a volatile organic solvent onto the insulation layer to wet the CNTs.
