The Effect of Grain Size-Secondary Electron Emission on Grain Growth in Dusty Plasma
Iraqi Journal of Physics, 2010 The calculation of the charge on an isolated dust grain immersed in plasma with different grain sizes is a challenging one, especially under moderately high plasma temperature when secondary electron emission significant.

Charging of Aggregate Grains in Astrophysical Environments
, 2013 The charging of dust grains in astrophysical environments has been investigated with the assumption these grains are homogeneous spheres. However, there is evidence which suggests many grains in astrophysical environments are irregularly-shaped ...

Scanning ultrafast electron microscopy [PDF]
, 2010 Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200

Carbon-oxygen surface formation enhances secondary electron yield in Cu, Ag and Au
Scientific Reports, 2022 First-principles calculations coupled with Monte Carlo simulations are used to probe the role of a surface CO monolayer formation on secondary electron emission (SEE) from Cu, Ag, and Au (110) materials.

Engineered surfaces to control secondary electron emission for multipactor suppression [PDF]
, 2016 A significant problem for space-based systems is multipactor - an avalanche of electrons caused by repeated secondary electron emission (SEE). The consequences of multipactor range from altering the operation of radio frequency (RF) devices to permanent ...

Non-thermal emission from old supernova remnants [PDF]
, 2007 We study the non-thermal emission from old shell-type supernova remnants (SNRs) on the frame of a time-dependent model. In this model, the time-dependent non-thermal spectra of both primary electrons and protons as well as secondary electron/positron ($e^

Secondary electron emission from sodium chloride, glass and aluminum oxide at various temperature [PDF]
The method of single impulses was used to measure the coefficients of the secondary electronic emission for 2 types of Al2O2, monocrystalline NaCl and glass at different temperatures and for different values of the energy of the primary electrons.
