摘要:
The present application relates to a method for making a carbon nanotube field emitter. A carbon nanotube film is drawn from the carbon nanotube array by a drawing tool. The carbon nanotube film includes a triangle region. A portion of the carbon nanotube film closed to the drawing tool is treated into a carbon nanotube wire including a vertex of the triangle region. The triangle region is cut from the carbon nanotube film by a laser beam along a cutting line. A distance between the vertex of the triangle region and the cutting line can be in a range from about 10 microns to about 5 millimeters.
