Abstract
The present application relates to a carbon nanotube field emitter. The carbon nanotube field emitter includes a carbon nanotube structure. The carbon nanotube structure includes a plurality of carbon nanotubes joined end-to-end by van der waals attractive force. The carbon nanotube structure has two joined portions, one portion is a triangle shaped carbon nanotube film, which is an electron emitting portion, the other portion is a carbon nanotube wire, which is a support portion.
