Secondary electron emission characteristics of Al2O3 coatings prepared by atomic layer deposition

AIP Advances, 2019
Secondary electron emission (SEE) plays a crucial role in the gain performance of devices, such as electron multipliers and microchannel plates (MCPs). Gain performance could be improved by increasing the secondary electron yield (SEY) of device surface.

Electron cascades and secondary electron emission in graphene under energetic ion irradiation [PDF]

Physical review B, 2020
Highly energetic ions traversing a two-dimensional material such as graphene produce strong electronic excitations. Electrons excited to energy states above the work function can give rise to secondary electron emission, reducing the amount of energy ...

Secondary electron emission from insulators and negative electron affinity semiconductors

Results in Physics, 2021
Based on expression of primary range R and the R at Epo ≥ 10.0 keV and L at Epo ≥ 1.0 keV calculated by ESTAR program [1], the method of obtaining formula for R at Epo ≥ 1.0 keV is presented; where Epo is incident energy of primary electron, and L is the

Secondary electron emission characteristics of the Al2O3/MgO double-layer structure prepared by atomic layer deposition

Ceramics International, 2021
As a secondary electron emission layer, an Al2O3/MgO double-layer structure is fabricated by atomic layer deposition (ALD) technology. The thickness range from 1 nm to 4 nm of the top Al2O3 layer deposited on 20 nm MgO creates a double-layer.

The Role of Elastic and Inelastic Electron Reflection in Multipactor Discharges. [PDF]

, 2005
In this brief, it is demonstrated that the inclusion of primary electron elastic and inelastic reflection from the surfaces of vacuum RF electronic systems can result in a multipactor discharge where under current techniques multipactor is predicted not ...

Photon and electron induced electron emission from solid surfaces

, 2007
The emission of electrons from solid surfaces under photon and electron impact is discussed. The focus of this contribution is on the transport of electrons from their point of generation inside the solid to the surface.
