Abstract:
1. A vacuuming sintering method for a carbon nanotube of a field display, comprising: attaching a cathode to an anode; disposing the attached cathode and anode on a heating element of a vacuum sintering furnace with cathode adjacent to the heating element, wherein each of the cathode and anode has at least one electrode lead connected to an external voltage source; reducing internal pressure of the vacuum sintering furnace, activating the heating element, and providing a voltage across the cathode and the anode, so as to generate an electric field between the cathode and the anode; switching off the voltage after the electric field is formed and continuing heating for a predetermined period of time; terminating heating and removing the attached cathode and anode from the vacuum sintering furnace, such that the carbon nanotube is formed parallel to the electric field and perpendicular to the cathode, or one end of the carbon nanotube is inclined towards the anode to advantage electron generation therefrom.
