Abstract
A field emission device includes a cathode and a carbon nanotube (CNT) gate electrode. The CNT gate electrode which is electrically insulated from the cathode includes a CNT layer and a dielectric layer. The CNT layer which has a surface includes a number of micropores. The dielectric layer is coated on the surface of the CNT layer and an inner wall of each of the micropores.
