Large Emission Current From Cnt Point Emitters Fabricated By The Free Standing Cnt Film
IDW'11: PROCEEDINGS OF THE 18TH INTERNATIONAL DISPLAY WORKSHOPS, VOLS 1-3(2011)
Abstract
Carbon nanotube (CNT) point emitters were fabricated by free standing CNT films. The point emitters showed large emission current up to 3.0 mA at the electric field of 2.34 V/mu m and good emission stability over 24 hr. Moreover, the emitted electrons were focused well without any focusing lens.
