  • Method for making carbon nanotube field emitter
    Patent number: 9171689
    Abstract: A method for making carbon nanotube field emitter includes providing a carbon nanotube array formed on a surface of a substrate. A plurality of carbon nanotubes of the carbon nanotube array is selected and pulled out a carbon nanotube film by a drawing tool, wherein the carbon nanotube film includes a plurality of carbon nanotubes oriented along a fixed direction. The carbon nanotube film is cut to a plurality of uniform carbon nanotube sub-films along the fixed direction. The plurality of carbon nanotube sub-films is treated to a plurality of carbon nanotube yarns. The plurality of carbon nanotube yarns is fixed on a surface of a conductive base, and cutting off the plurality of carbon nanotube yarns by a laser beam, to form a carbon nanotube field emitter.
