Abstract: |
A field emission cathode consists of a numbers of electronic emission bodies and a numbers of inductive carriers for bearing those electronic emission bodies. It features that inductive carrier is a mesh structure formed by a numbers of inductive bearing columns and a numbers of electronic emission bodies are formed on surface of each inductive bearing column separately for decreasing field emission voltage of the whole cathode and for improving emission performance. |
