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 yields from spacecraft materials [PDF]

, 1985
Photoyields and secondary electron emission (SEE) characteristics were determined under UHV conditions for a group of insulating materials used in spacecraft applications. The SEE studies were carried out with a pulsed primary beam while photoyields were

Analysis of multipacting threshold sensitivity to the random distributions of the secondary electron yield parameters

Scientific Reports
The way multipacting develops, depends strongly on the secondary emission property of the surface material. The knowledge of secondary electron yield is crucial for accurate prediction of the multipacting threshold. Variations in secondary electron yield

Secondary Electron Emission

, 1982
The paper surveys experimental and theoretical work on secondary electrons released by primary electrons with energies greater than 100 eV with regard to electron microscopy and microanalysis. The secondary electron emission is a rather complex phenomenon: 1) The interaction of energetic primary electrons with material and the excitation of electrons ...

Measurements of the Secondary Electron Emission of Some Insulators

, 2013
Charging up the surface of an insulator after beam impact can lead either to reverse sign of field between the surface and collector of electrons for case of thick sample or appearance of very high internal field for thin films.
