    摘要: Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.

    摘要: A system and method is available for fabricating a field emitter device, where in an emitter material, such as copper, is deposited over a resistive layer which has been deposited upon a substrate. Two ion beam sources are utilized. The first ion beam source is directed at a target material, such as molybdenum, for sputtering molybdenum onto the emitter material. The second ion beam source is utilized to etch the emitter material to produce cones or micro-tips. A low work function material, such as amorphous diamond, is then deposited over the micro-tips.
