Abstract:
A field emission electron source includes a CNT needle and a conductive base. The CNT needle has an end portion and a broken end portion; the end portion is contacted with and electrically connected to a surface of the conductive base. The CNTs at the broken end portion form a taper-shape structure, wherein one CNT protrudes and is higher than the adjacent CNTs.
