Secondary electron emission and yield spectra of metals from Monte Carlo simulations and experiments
2019
In this work, we present a computational method, based on the Monte Carlo statistical approach,
for calculating electron energy emission and yield spectra of metals, such as copper, silver and
gold. The calculation of these observables proceeds via the Mott theory to deal with the elastic
scattering processes, and by using the Ritchie dielectric approach to model the electron inelastic
scattering events. In the latter case, the dielectric function, which represents the starting point
for the evaluation of the energy loss, is obtained from experimental reflection electron energy loss
spectra. The generation of secondary electrons upon ionization of the samples is also implemented
in the calculation. A remarkable agreement is obtained between both theoretical and experimental
electron emission spectra and yield curves.
