摘要： An aligned double-walled carbon nanotube bulk structure composed of plural aligned double-walled carbon nanotubes and having a height of 0.1 μm or more and a double-walled carbon nanotube are produced by chemically vapor depositing (CVD) a carbon nanotube in the presence of a metal catalyst with controlled particle size and thickness, preferably in the presence of moisture. According to this, it is possible to provide a double-walled nanotube which is free from inclusion of the catalyst, has high purity, is easy to control the alignment and growth, is able to achieve the fabrication through the formation of a bulk structure and has excellent electron emission characteristic (particularly, a double-walled carbon nanotube bulk structure) and also to provide a production technology thereof.
