Abstract: We present detailed comparisons of calculated inelastic mean‐free paths (IMFPs) of electrons with energies up to 10 keV from the full Penn algorithm (FPA) model and the Mermin model using prototypical Drude‐type energy‐loss functions (ELFs).… read more here.

Abstract: Stopping power (SP) and inelastic mean free path (IMFP) of electrons in Ti, Fe, Ni, and Pd have been determined by using dielectric models. We have used energy loss function (ELF) determined from quantitative analysis… read more here.

Abstract: ABSTRACT The TPP-2M formula is the most popular empirical formula for the estimation of the electron inelastic mean free paths (IMFPs) in solids from several simple material parameters. The TPP-2M formula, however, poorly describes several… read more here.
