ABSTRACT:
A field emission light source (100) includes: a cathode (111); a nucleation layer (112) formed on the cathode; a field emission portion (102) formed on the nucleation layer; and a light-permeable anode (117) arranged over the cathode. The field emission portion includes an isolating layer (113) formed on the cathode; a plurality of isolating posts (114) disposed on the isolating layer; and a plurality of field emitters (115) located on the respective isolating posts. The field emitters contain molybdenum. The isolating posts contain silicon carbon. Preferably, the field emitter has a diameter ranging from about 0.5 nanometers to 10 nanometers.
