<p><P>PROBLEM TO BE SOLVED: To provide an electron emitter material excelling in durability and capable of large-current field electron emission; and an electron emission application device using such an electron emitter material. <P>SOLUTION: This electron emitter material is formed by adsorbing diamond powder to a surface of carbon foam, and thereafter growing diamond on the carbon foam by a chemical vapor deposition (CVD) treatment. In the electron emitter material, the diamond powder is nano-diamond powder. This electron emission application device is composed by installing an electron extracting grid electrode on the front surface of the electron emitter material. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
