Induced electrical property changes in single walled carbon nanotubes by electromagnetic radiation

A process for selectively changing the diameter and morphology of a carbon nanotube, comprising:

• placing a carbon nanotube in a vacuum area;
• creating a vacuum in the vacuum area;
• and
• directing a microwave at a selected frequency and power setting at the carbon nanotube.

A process for selectively changing the diameter and morphology of a carbon nanotube, comprising:

• placing a carbon nanotube in a vacuum area;
• creating a vacuum with a pressure of about 10−4 to 10−9 torr in the vacuum area;
• and
• directing a microwave frequency of between 0.1 GHz and 100 GHz and a power output of between 0.001 Watt and 1,500 Watts at the carbon nanotube.
