Abstract :
Atomically sharp, high density tungsten nanotip arrays are fabricated by a novel nanocasting technique. Such emitter arrays show excellent field emission properties with a low turn-on field, a high field enhancement factor and good emission stability. They also have better vacuum tolerance than most field emission nanostructures due to a closer cathode-anode spacing allowed by the perfect tip alignment and uniform height distribution.
