Field emission from sulfur doped nanocrystalline diamond films is characterized by intense emission sites with nm scale diameters. Field emission measurements were obtained at room temperature and analyzed in terms of the Fowler–Nordheim expression

Electron emission can be described by thermionic and field effects or a combination of both and can be characterized by the laws of Richardson–Dushman and Fowler–Nordheim, respectively. Nano-crystal graphitic films exhibit a film morphology compr

Room temperature electron emission from carbon and diamond films is usually based on tunnelling effects and can be implemented by application of an electric field to the emitter surface. Field emission from nanocrystalline thin films exhibits intense

Sulfur doped nanocrystalline diamond films, like other nanostructured carbon films, exhibit electron emission characterized by a spatial non-uniformity of the field enhancement factor. While field emission effects are observed at room temperature, an

Molecular oxygen and hydrogen ions were scattered at grazing incidence from several diamond-like carbon (DLC) surfaces in the energy range from 190 eV to 2400 eV. Most surfaces were hydrogen terminated. For incident positive oxygen ions, scattered ne

Electron emission from carbon materials has been based on two effects: field enhancement from conducting nanostructures and barrier lowering due to the negative electron affinity of diamond surfaces. Moreover, n-type doping with P and N can enable a
