| Abstract: | Development and application of nanotube are a new branch of science and technology. The aligned nanotube thin films are substantially strong, and chemically inertial with their onset field low and the emission current strong. All of these characteristics reveal that the carbon nanotube film has a bright future in field emission. This paper introduces several production techniques of nanotubes, research on and application of the nanotube in field emission as well as its latest development. Merits and defects of different production techniques and characteristics of field emission are compared, and the defects present as well as the development prospects of the nanotube used in field emission are also analyzed. |
