Abstract
A method of encapsulating a material in a carbon nanotube comprising generating a vapor of the material to be encapsulated, generating a hydrogen arc discharge that discharges encapsulating products, and contacting the vapor of the material and the products discharged from the hydrogen arc discharge proximate a surface to encapsulate the material in a carbon nanotube. A carbon nanotube encapsulating a metallic material (e.g. copper), a semi-conductor material (e.g. germanium) and other materials can be produced.
