METHOD OF FORMING CARBON NANO-THREAD - NIPPON TELEGRAPH & TELEPHONE

Title:

METHOD OF FORMING CARBON NANO-THREAD

Document Type and Number:

Japanese Patent JP2004217456

Kind Code:

A

Abstract:

To provide a method for forming a carbon nano-thread to prepare a carbon nano-thread excellent in linearity.

A carbon nanotube 3 held in a space is irradiated with gallium ion beam going through the carbon nanotube 3. The carbon nanotube 3 held in the space bridges finely structured micropillars 2 and grows. A carbon nanotube 3 other than the one held in the space is removed by the irradiation of gallium ion beam. The carbon nanotube 3 is heated during or after the irradiation of gallium ion beam. As a result, the carbon nanotube 3 is made amorphous and improved in linearity by irradiating the carbon nanotube 3 held in the space with gallium ion beam.
