Inelastic scattering of electrons in solids from a generalized oscillator strength model using optical and photoelectric data
TLDR
In this article, a generalized oscillator strength model based on optical and photoelectric data is proposed to compute the mean free paths and stopping powers of electrons in solids for four materials (Al, Si, Cu and Au) and for electrons with energies from 10 eV to 10 keV.Abstract:
Inelastic scattering of electrons in solids is computed from a generalized oscillator strength model based on optical and photoelectric data. The optical oscillator strength is extended into the non-zero momentum transfer region by using free-electron gas dispersion for the weakly bound electrons. The applicability of this method to non-conduction valence electrons and to inner shells is discussed. A different extension method, which reproduces ionization thresholds, is used for inner-shell ionization. The calculations are simplified by using a two-modes model for the Lindhard theory of the free-electron gas. Exchange effects are accounted for by means of a modified Ochkur approximation. Inelastic mean free paths and stopping powers obtained from this optical-data model for four materials (Al, Si, Cu and Au) and for electrons with energies from 10 eV to 10 keV are presented.read more
