Electron multiplier concentrator for integrated field-emission electronics

Technical Physics Letters, 2010
We describe the design and technology of manufacturing an electron multiplier concentrator (EMC) that plays the role of a field-emission cathode capable of ensuring a significantly greater current density as compared to that provided by the existing electron emitters.

Electron field emission from microtip arrays

Vacuum, 2008
Abstract Electron field emission measurements from structurized cathodes was reported. Silicon (Si) and boron-doped silicon carbide (SiC:B) had been chosen as a base materials for microtip field emission arrays (FEA). Each of single silicon FEAs has been covered by a thin metal layer using chromium (Cr), titanium (Ti) or platinum (Pt) to reduce the ...

A graded electron affinity field emission electron source

IVMC '95. Eighth International Vacuum Microelectronics Conference. Technical Digest (Cat. No.TH8012), 2002
We report electron affinity measurements suggesting that Ga/sub 1-x/Al/sub x/N has the characteristics needed to create an improved field emitter. By grading the composition from low to high Al mole fraction within a thin layer at the surface of a field emitter, the uniformity, noise, and emission modulation characteristics may be improved.

Field electron emission theory

2017
This conference paper provides an overview of the material presented in two field electron emission tutorial lectures given at the 2016 Young Researchers' School in Vacuum Microand NanoElectronics, held in Saint-Petersburg on October 5-6 2016. This paper aims to indicate the scope and structure of the tutorials, and also where some of the related ...

Correlated electron tunneling during the field electron emission

Technical Physics Letters, 2001
Elementary events of correlated electron tunneling from very small regions of a hollow metal emitter were detected. The most significant microscopic and macroscopic parameters favoring the appearance of multiparticle tunneling effects are considered.

Field Emission and Electron Microscopy.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada
An overview and new results are presented of the investigations carried out in the last 5 years on nano-sized tips by means of electron microscopy, an electron optical bench, and computation. Tungsten and, in particular, carbon nano-tips prepared by carbon contamination in a scanning electron microscope, were studied for applications as field-emission ...

Emitter for field ionization and field electron emission

International Journal of Mass Spectrometry and Ion Physics, 1983
Abstract An emitter consists of a carrier of metal, e.g. a wire, with protruding crystalline whiskers of a tungsten bronze (ref. 1), (ref. 2). The advantages of these emitters over previously known are: 1. Much thicker wires can be used, 0,1 mm and more in comparison with at most 0,01 mm. 2.

Electron Emission from Metals in Intense Electron Fields

1929
The behavior of a fine wire placed axially in a cylindrical anode is investigated. A brief account is given of the more recent literature dealing with the subject. A quartz tube which has been found particularly suitable and convenient is described.
