摘要:
A carbon nanotube has a carbon network film of polycrystalline structure divided into crystal regions along the axis of the tube, and the length along the tube axis of each crystal region preferably ranges from 3 to 6 nm. An electron source includes a carbon nanotube having a cylindrical shape and the end of which on the substrate side is closed and disposed in a fine hole. The end on the substrate side of the tube is firmly adhered to the substrate. The carbon nanotube is produced by a method in which carbon is deposited under the condition that no metal catalyst is present in the fine hole and produced by a method in which after the carbon deposition the end of the carbon deposition film is modified by etching the carbon deposition film using a plasma. Therefore, an electron source excellent in the evenness of field emission characteristics in a field emission region (pixel) in the device plane and driven with low voltage can be provided, and a display operated with ultralow power consumption exhibiting ultrahigh luminance can be provided.

An ejector is provided with an interior surface wetting device for introducing a cleaning liquid into a suction chamber of the ejector to form a thin wall of the cleaning liquid covering an interior surface of the ejector. The interior surface wetting device includes a cleaning liquid inlet opening to be fluidly connected to a source of cleaning liquid and a cleaning liquid outlet opening for introducing the cleaning liquid into a suction chamber. The wetting device may be in the form of a pipe which extends from the outside of the ejector into the suction chamber to supply a cleaning liquid to a desired portion in the suction chamber.

A carbon nanotube composite material contains a carbon nanotube and a continuous layer of a metal covering the inner surface of the carbon nanotube. It is produced by forming a metallic matrix layer and treating the metallic matrix layer to form plural nanoholes in the metallic matrix layer to thereby form a nanohole structure, the nanoholes extending in a direction substantially perpendicular to the plane of the metallic matrix layer; forming carbon nanotubes inside the nanoholes; and covering inner surfaces of the carbon nanotubes with a continuous layer of a metal. It has a well controlled small size, has excellent and uniform physical properties, is resistant to oxidation of the metal with time, is highly chemically stable, has good durability enabling repetitive use, has good coatability, high wettability and dispersibility with other materials, is easily chemically modified, is easily handled and is useful in various fields.
