摘要:
This invention includes field emitters, in particular, electron field emitters with metal oxide nanoscale, aligned and sharped-tip emitter structures, the metal oxide emitter structures being a plurality of carbon nanostructures supported by and projecting from a substrate and including a metal oxide coating overlying the surfaces of the plurality of carbon nanostructures.
摘要:
This invention discloses novel field emitters which exhibit improved emission characteristics combined with improved emitter stability, in particular, new types of carbide or nitride based electron field emitters with desirable nanoscale, aligned and sharped-tip emitter structures.
摘要:
Field emitter arrays with split gates and methods for operating the same. A field emitter array may include one or more pairs of split gates, each connected to a corresponding voltage source, the split gates forming at least one gate hole for at least one emitter tip. Voltages, for example, AC voltages V1 and V2 may be applied to the split gates to perform one- or two-dimensional scanning or tilting depending on a ratio of V1 and V2.

摘要:
Nanotube assemblies and methods for manufacturing the same, including one or more protective layers. A nanotube assembly may include a substrate, a nanotube array, formed on the substrate, and a protective layer, formed on a first area of the substrate where the nanotube array is not, the protective layer reducing the formation of nanocones, and promoting the formation of nanotubes, which make up the nanotube array.

摘要:
A lithography system and method for operating the same. The lithography system may include a cathode adapted to emit an electron beam, a beam-homogenizing structure, capable of increasing at least one of the uniformity and energetic of the electron beam, and a mask adapted to accelerate the electron beam to form a pattern on a wafer.
