Abstract
A method for making a carbon nanotube field emitter is provided. A carbon nanotube array and a cathode substrate are provided. The carbon nanotube array is heated to form a graphitized carbon nanotube array. A conductive adhesive layer is formed on a surface of the cathode substrate. One end of the graphitized carbon nanotube array is contact with the conductive adhesive layer. The conductive adhesive layer is solidified to fix the graphitized carbon nanotube array on the cathode substrate.
