ABSTRACT:
This invention relates to a fabrication method of field emission device by using a carbon nano-tubes and, more particularly, to a fabrication method of field emission device by using the carbon nano-tubes, gathering much attention as a new material, as a field emission tips which have thin and stiff edges so that a threshold voltage required for emitting electron of the field emission device is to be lowered drastically. This invention provides a fabrication method of the field emission device using a thermally and chemically stable carbon nano-tubes, which have very stiff and nano-meter-thick edges, as a field emission tips so that the field emission device using the carbon nano-tubes as the tips, which have an excellent electron beam coherency, can emit electrons at a very low voltage and very stable during a long period.
