Electron emission elements |
摘要 |
An electron emission element comprises a P-type semiconductor substrate and electrodes formed on both ends of the semiconductor substrate. A voltage is applied between said electrodes. The P-type semiconductor substrate is irradiated with light to emit the electrons, generated in the P-type semiconductor substrate by photoexcitation, from an electron emitting face at an end of the P-type semiconductor substrate.
