Description:

We have calculated IMFPs for 41 elemental solids, 44 inorganic compounds and 12 organic compounds at equal energy intervals on a logarithmic scale corresponding to increments of 10% from 10 eV to 200 keV. These calculations were made with ELFs using the relativistic full Penn algorithm. The ELFs for semiconductors and several inorganic compounds were obtained from first-principles calculations with the WIEN2K and FEFF codes from 1 eV to 1 MeV. Our calculated IMFPs could be fitted to a modified relativistic Bethe equation for inelastic scattering of electron in matter for energies from 50 eV to 200 keV. The averageRMS deviation in these fits was 0.8% for the 41 elemental solids. The new IMFPs were also compared with IMFPs from the predictive TPP-2M equation.
