    摘要: There is provided a method for preparing a single layer carbon nano-tube stably and in high preparation efficiency. Helium is introduced from a gas inlet 19 while exhausting inside a vacuum chamber 11 by means of a rotary pump 12 to prepare an atmosphere of rare gas. DC arc discharge is established between a metal-added carbon electrode to which a single metal is added 13 and a metal-added carbon electrode to which a single metal the kind of which is different from that of the former metal is added 14 by the use of a discharge power source apparatus 17. Carbon and metals are evaporated from both electrodes, and the metals are alloyed to act as a catalyst to the carbon and the single layer carbon nano-tube is prepared.

    摘要: A method is herein disclosed for preparing a film of a carbon nano-tube to obtain a low cost field emission source using a carbon nano-tube. A single-wall carbon nano-tube is placed together with acetone in a beaker, to which ultrasonic wave is applied to disperse the single-wall carbon nano-tube in acetone. Thereafter, acetone is evaporated spontaneously to deposit the single-wall carbon nano-tube on a copper plate placed in the beaker. The copper plate on the surface of which the single-wall carbon nano-tube is deposited is used for a cathode of an electronic tube.
