Abstract :
Field emission characteristics of a graphite nanofiber (GNF) emitter used in FED were examined using a scanning Faraday cup emission profiler. The current density of emitted electrons changed considerably over the emitting area at a low field, as high as two orders in intensity in a measuring emitter area of 1 mm2. However, uniformity was significantly improved due to current saturation at a high field. This paper discusses the current saturation in field emission of GNF from the space-charge effect of emitted electrons
