| titleOfInvention | Monochromatic electron beam source and manufacturing method thereof |
| abstract | (57) [Abstract] [Purpose] To obtain an electron beam source with a narrow energy width and a stable electron flow even with voltage fluctuations. [Structure] A plurality of coating films 2 are formed on a needle-shaped cathode conductor 1. 3 is provided, and a voltage 6 is applied between the anode 5 and the opposing anode 5 to form the quantum well layer 3 and the energy barrier capacitor layers 2 and 7 that sandwich the quantum well layer 3 at the tip of the cathode. A stable monochromatic electron beam is emitted by the resonant tunneling phenomenon via 8. |
