Abstract :
The new composites of carbon nanotube with silicon dioxide (SiO2) nanoparticle for FED cathode is studied. It has significantly improved emission current density property and stable emission characterization of cathode, because it has higher enhancement factor and less shield-effect by adjusting silicon nanoparticle content. The results indicated that when about 80 wt% CNT is optimum content, the current density at the electric field 2 V/μm is 56 mA/mm2, the turn-on field of the CNTs cathode was about 0.71 V/μm. The fluctuation of emission current is less than 3% for three hours.
