摘要：A field emitter element comprising a bottom layer of material shaping theoverall emitter element, and a top layer of low work function material or otherwise ofhigh electron emissivity characteristic. The low work function top layer preferably isshaped to a sharp point. The bottom layer may be formed of a material such as tantalum,molybdenum, gold, or silicon (or alloys thereof), and the top layer may be formed of amaterial such as Cr.sub.3 Si, Cr.sub.3 Si.sub.2, CrSI.sub.2, Nb.sub.3 Si. sub.2, Nb, Cr.sub.2O.sub.3 or SiC. In a specific aspect, at least one of the first and second emitter materials ischromium oxide (Cr.sub.2 O.sub. 3). In another variant, the first emitter material is aninsulator of leaky dielectric, e.g., SiO with a 10-60% Cr by weight based on the weight ofSiO, and the second emitter material is SiO+50-90% Cr by weight, based on the weight ofSiO.
