ABSTRACT:
A method for manufacturing a field emission electron source includes: (a) Providing a carbon nanotube (CNT) film, the CNT film has a plurality of CNTs, the CNTs are aligned along a same direction; a first electrode and a second electrode. (b) Fixing the two opposite sides of the CNT film on the first electrode and the second electrode, the CNTs in the CNT film extending from the first electrode to the second electrode. (c) Treating the CNT film with an organic solvent to form at least one CNT string. (d) Applying a voltage between two opposite ends of the CNT string until the CNT string snaps, thereby at least one CNT needle, the CNT needle has an end portion and a broken end portion. (e) Securing the CNT needle to a conductive base by attaching the end portion of the CNT needle to the conductive base.
