Vacuum-plasma processes at extreme field emission in diamond electron sources

Background and Objectives: The use of high-current field electron sources that satisfy various circuitry requirements as a part of electronic devices for various purposes suggests the possibility of matching their operation modes with the operating characteristics of the devices, as well as high reproducibility of emission parameters, stability and the necessary resource of reliability and durability.

Carbon Film Nanocomposite for High-Current Field Electron Sources

Background and Objectives: Requirements and problems are formulated when creating cathode materials for high-current emission electronics. It has been shown that to create autocathodes with a current density of up to 100 A/cm2 and above, the development of new nanostructured carbon materials with a surface density of nanodiamond edges of not less than 106–108 cm-2 is necessary.
