Abstract :
The enhancement of electron emission by laser illumination of a metal-oxide-semiconductor (MOS) cathode based on nanocrystalline silicon was investigated. An increase of the emission current under blue laser irradiation was proportional to the incident laser power. The influence of light modulation on the emission current was also investigated. We have obtained a modulated electron beam by laser pulses.
