Ultralow Secondary Electron Emission of Graphene

open access: yesACS Nano, 2011
In order to ensure that vacuum electronic devices work with high overall efficiency, it is required to use materials with low secondary electron emission to fabricate or coat collectors, grids, and envelope walls of the devices. We report that the secondary electron yields of monolayer graphenes are ultralow, comparable with the lowest yields of the ...

Secondary electron emission properties [PDF]

open access: yesPhilips Journal of Research, 1996
Abstract In this paper an introduction is given to secondary electron emission properties. It is shown that the reduced secondary emission yield δ δ m as a function of the reduced primary energy E p E m can be described by a universal curve.
