Secondary electron field emission

Physica Status Solidi (a), 1988
Secondary electron field emission (SEFE) is based on Fowler-Nordheim tunneling from conducting substrates into thin insulating layers due to their strongly positive charging-up during electron bombardment. This self-consistent charging-up process is demonstrated by a computer simulation.

Electron field emission source

4th IEEE International Conference on Vacuum Electronics, 2003, 2004
In this paper the new design of the electron field emission source for surface analyzers, displays, X-ray tubes and microwave devices is proposed. The advantages of the field emission source are also provided. Several variants of the field emission sources have been produced and tested.

A Field Emission Electron Microscope

Proceedings, annual meeting, Electron Microscopy Society of America, 1971
We have developed a field emission electron microscope. Although field emission gun requires ultra high vacuum and skillful technique, it brings about the favorable characteristics of high brightness and small energy spread. This characteristics will enable a significant progress in coherent electron optics and high resolution electron microscopy ...

Field electron emission from nanodiamond

Technical Physics Letters, 2009
Nanodiamond (ND) films on silicon substrates have been synthesized by plasmachemical deposition (PCD). Films with minimum differences in the structure and morphology, which were obtained by varying the PCD process parameters, exhibited significantly (several orders in magnitude) different field-emission currents.
