Electronic stopping power of compounds was calculated by using the Thomas-Fermi-Dirac-Weizsäcker density functional. Bragg's rule was employed to determine stopping power of compounds from the elemental stopping power results. Calculations were done for Be, B, O, and Si ions in Al₂O₃, SiO₂, and CO₂ targets by using the Thomas-Fermi-Dirac-Weizsäcker density functional. The obtained results were compared with other Thomas-Fermi based theoretical calculations and show that using Thomas-Fermi-Dirac-Weizsäcker density functional in stopping power calculations yields reasonably accurate results in especially light systems (with respect to the number of electrons in the system).
