    Abstract: Based on designs concerning boron nitride thin-films each including boron nitride crystals in acute-ended shapes excellent in field electron emission properties, and designs of emitters adopting such thin-films, it is aimed at appropriately controlling a distribution state of such crystals to thereby provide an emitter having an excellent efficiency and thus requiring only a lower threshold electric field for electron emission.In a design of a boron nitride thin-film emitter comprising crystals that are each represented by a general formula BN, that each include sp3 bonded boron nitride, sp2 bonded boron nitride, or a mixture thereof, and that each exhibit an acute-ended shape excellent in field electron emission property; there is controlled an angle of a substrate relative to a reaction gas flow upon deposition of the emitter from a vapor phase, thereby controlling a distribution state of the crystals over a surface of the thin-film.

    Abstract: Provided is a charged particle beam apparatus, which can emit a stable electron beam, having high brightness and a narrow energy width. The charged particle beam apparatus comprises a field emission electron source, electrodes for applying an electric field to the field emission electron source, and a vaccume exhaust unit for keeping the pressure around the field emission electron source at 1 10−8 Pa or less. The apparatus is so constituted as to use such one of the electron beams emitted as has an electron-beam-center radiation angle of 1 10−2 str or less, and to use the electric current thereof, the second order differentiation of which is negative or zero with respect to the time, and which reduces at a rate of 10% or less per hour. The charged particle beam apparatus further comprises a heating unit for the field emission electron source, and a detection unit for the electric current of the electron beam. The field emission electron source is repeatedly heated to keep the electric current of the electron beam to be emitted, at a predetermined value or higher.

    Abstract: Field emission devices comprising carbon nanotube mats which have been treated with laser or plasma are provided. Mats are formed from carbon nanotubes, also known as carbon fibrils, which are vermicular carbon deposits having diameters of less than about one micron. The carbon nanotube mats are then subjected to laser or plasma treatment. The treated carbon nanotube mat results in improved field emission performance as either a field emission cathode or as part of a field emission device.

    Abstract: High-current density field emission sources using arrays of nanofeatures bundles and methods of manufacturing such field emission sources are provided. Variable field emission performance is provided with the variance in the bundle diameter and the inter-bundle spacing, and optimal geometries for the lithographically patterned arrays were determined. Arrays of 1-μm and 2-μm diameter multi-walled carbon nanotube bundles spaced 5 μm apart (edge-to-edge spacing) were identified as the most optimum combination, routinely producing 1.5 to 1.8 A/cm2 at low electric fields of approximately 4 V/μm, rising to >6 A/cm2 at 20 V/μm over a ˜100-μm-diameter area.
