Emission characteristic of diamond-tip FEA fabricated by transfer mold technique

Abstract

Stripe-shaped diamond-tip field emitter arrays were fabricated by using transfer mold technique. The tip radius of each diamond emitter was about 300 angstroms. The current density of 800 μA/cm2 was obtained from the current-voltage measurement of the diamond-tip field emitter arrays. The emission current was measured under the pressure of 1×10-4, 1×10-5, 1×10-6 Torr, respectively. No difference in emission characteristics of the field emitter arrays under different pressure condition was observed.
