Abstract :
Smith-Purcell radiation (SPR) was generated from a single-tip Si field emitter at a low power level. Single-tip Si field emitters were fabricated using reactive ion etching and thermal oxidation sharpening. Radiation measurements were performed through a viewing port in the visible spectra. SPR was successfully observed at 300-900 nm wavelength, 20-200 nA beam current and 25-30 kV accelerating voltage.
