Influence of the description of the target energy‐loss function on the energy loss of swift projectiles

Surface and Interface Analysis, 2008
Abstract The optical energy‐loss function (ELF) of Au and Al, obtained from experiments, is extended to finite wavenumber k using three different widely used models, namely, with the Mermin type ELFs with generalized oscillator strengths (MELF‐GOS) model, the extended Drude ...

Energy dependence of the energy loss function parametrization of indium in the Drude–Lindhard model

Surface and Interface Analysis, 2014
The energy loss function (ELF) is a key parameter for the calculations of energy losses undergone by electrons in matter. It is often the only input in the calculations performed within the models based on the semi‐classical dielectric response theory. Its perfect knowledge is thus of primordial importance.

Wavenumber dependence of the energy loss function of graphite and aluminium

Journal of Electron Spectroscopy and Related Phenomena, 1996
Abstract The energy loss function of a material is a key parameter in the dielectric formalism used to describe the optical spectra and the excitations produced by swift charges in solids. Modelling the experimental energy loss function as a sum of Mermin type functions in the optical limit (i.e., at zero momentum transfer), we have calculated its ...

Effective energy loss function of silver derived from reflection electron energy loss spectra

Surface and Interface Analysis, 2006
Abstract The electron inelastic scattering in silver is studied both experimentally and theoretically. The reflection electron energy loss spectroscopy (REELS) spectra were measured using the ESA‐31. It is shown that the surface excitation is enhanced with decreasing primary energy.

Kramers–Kronig transform for the surface energy loss function

Journal of Electron Spectroscopy and Related Phenomena, 2005
A new pair of Kramers–Kronig (KK) dispersion relationships for the transformation of surface energy loss function Im[−1/(e + 1)] has been proposed. The validity of the new surface KK transform is confirmed, using both a Lorentz oscillator model and the surface energy loss functions determined from the experimental complex dielectric function of SrTiO3 ...

Energy loss functions for electron energy loss spectroscopy

Surface Science, 1999
Losses to surface excitations affect experimental data in several different kinds of spectroscopies and have been considered in detail by various workers. We discuss and compare calculations using commonly assumed response functions. The boundary (begrenzung) effect, originating in the orthogonality of surface and bulk eigenmodes, manifests interesting
