General Rules Governing the Highly Efficient Growth of Carbon Nanotubes

The key to highly efficient growth of carbon nanotubes includes two essential ingredients in the growth ambient: a carbon source that does not contain oxygen and a minute quantity of a secondary gas, which does contain oxygen, that acts as a growth enhancer. These and other general rules governing the growth of carbon nanotubes and the fundamental reasons from which they arise are presented.
