Abstract
A composite carbon nanotube structure comprises a first carbon nanotube structure and a second carbon nanotube structure. The first carbon nanotube structure includes a number of first carbon nanotubes extending substantially along the same direction and joined end-to-end by van der Waals force. The second carbon nanotube structure includes a number of second carbon nanotubes extending from a surface of the first carbon nanotube structure.
