| Research Abstract |
Application of plasmon resonance to electron field emission has been studied. Emission characteristics of gold sharp tip formed on electrochemically-sharpened tungsten apex were investigated under laser irradiation at several wavelengths. Electron beam current was maximized under irradiation at the plasmon-resonant wavelength, and optically emission control was demonstrated. These study clarified the mechanism of plasmon-resonant field emission, and the maximum enhancement factor of 217 was achieved. Field emitter array based on this principle was fabricated.
