Abstract

An application of non-crystal diamond is disclosed. It can emit the greatest deal of electrons in vacuum by supplying the lowest energy to it. It contains the carbon atoms (at least 90%) and has a emitting surface with the roughness of 10-10000nm. It can be used for various vacuum devices such as switch, laser diode, etc.

Description

[0001] This application is a divisional application with the application number 03148262.7, the application date is June 17, 2003, and the invention title is "amorphous diamond material and its manufacturing method and application". technical field [0002] The present invention relates primarily to devices for the application of amorphous diamond materials, in particular devices for generating electrons in a diamond-like carbon material. This application covers physics, chemistry, electronics and materials science. Background technique [0003] Thermal emission (Thermiomic Emission) and field emission (Field Emission) have already had many different applications, such as cathode ray tube (Cathode Ray Tube), field emission display (Field Emission Display). [0004] Usually thermal emission refers to the ejection of electrons by heating. Field emission refers to the tunneling and ejection of electrons driven by an electric field. 这些装置的例子以及描述包括下述的美国专利6,229,083;6,204,595;6,103...
