The displacement energies of cations in perovskite (CaTiO3)

High angular resolution electron channelling X-ray spectroscopy (HARECXS) was used to monitor the intensity ratio of Ca Kα/Ti Kα X-rays emitted by perovskite (CaTiO3) as a function of incident electron beam orientation. The collected HARECXS data suggest that the displacement energies of calcium and titanium in perovskite (CaTiO3) are 82 ± 11 eV and 69 ± 9 eV, respectively. These values are approximately 40% larger than those currently used to convert ion doses applied to oxides into dpa using SRIM.
