Secondary electron emission yield in the limit of low electron energy

, 2013
Secondary electron emission (SEE) from solids plays an important role in many areas of science and technology.1 In recent years, there has been renewed interest in the experimental and theoretical studies of SEE.

Compact Electron Gun Based on Secondary Emission Through Ionic Bombardment

Sensors, 2011
We present a new compact electron gun based on the secondary emission through ionic bombardment principle. The driving parameters to develop such a gun are to obtain a quite small electron gun for an in-flight instrument performing Electron Beam ...

The Influence of Secondary Electron Emission and Electron Reflection on a Capacitively Coupled Oxygen Discharge

Atoms, 2018
The one-dimensional object-oriented particle-in-cell Monte Carlo collision code oopd1 is applied to explore the role of secondary electron emission and electron reflection on the properties of the capacitively-coupled oxygen discharge.

Calculation of secondary electron emission yields from low-energy electron deposition in tungsten surfaces

, 2017
We present calculations of secondary electron emission (SEE) yields in tungsten as a function of primary electron energies between 50 eV and 1 keV and incidence angles between 0 and 90{\deg}.

Secondary electron emission and photoelectric emission with account of excited electrons’ moving backward emission surface

Results in Physics
From existing old photoelectric emission PEE and secondary electron emission SEE models and the process that 50 % excited electrons are treated as as those moving backward emission surface, this study develops new SEE model for negative electron affinity

Secondary-electron emission from hydrogen-terminated diamond: Experiments and model

Physical Review Special Topics. Accelerators and Beams, 2011
A hydrogen-terminated diamond is a proven efficient electron emitter that can support emission of high average current. Several factors dictate the amplifier’s gain: the number of secondary electrons created at their point of entry into the diamond, the ...

Novel types of anti-ecloud surfaces

, 2013
In high power RF devices for space, secondary electron emission appears as the main parameter governing the multipactor effect and as well as the e-cloud in large accelerators.

Reversible Ion Induced Modification of Consequent Secondary Electron Emission in Porous Silicon [PDF]

, 2009
We report measurements of secondary electron emission (SEE) induced by electron and ion bombardment on porous silicon (PS). We found that electron induced emission is strongly reduced by ion bombardment, and that this reduction is reversible.

A study of secondary electron emission from semiconductors and insulators

AIP Advances, 2018
No rude approximations were made in the course of deducing formula for B(χ, Eg) as a function of parameters of secondary electron emission SEE; where B(χ, Eg) is the probability that an internal secondary electron escapes into vacuum upon reaching the ...
