“…The potential materials for immobilization of nuclear waste must be able to endure extreme radiation environment associated with α-decay of the actinides and β-decay of the fission products. In the previous studies, several research groups have performed ion beam irradiations on SrTiO 3 to study its radiation tolerance [12][13][14][15][16]. An irradiation-induced crystalline to amorphous phase transformation was observed on SrTiO 3 , and quantitatively studies on the critical dose and temperature for amorphization were already reported [12,14,16].…”

The hot‐forging technique was used to obtain both the n = 2 (Sr3Ti2O7) and n = ∞ (SrTiO3) members of Ruddlesden‐Popper phase Srn+1TinO3n+1. Pure phase and high density (>95% theoretical) materials were achieved using this technique. These polycrystalline samples were irradiated with 200 keV He ions to a fluence of 2×1021 ion/m2 (corresponding to a peak dose at 5 dpa) at room temperature to study radiation damage effects. Microstructural investigation on pristine and irradiated samples was performed using grazing incidence X‐ray diffraction (GIXRD) and transmission electron microscopy (TEM). Three phenomena are revealed upon comparing prisXtine versus irradiated samples. First, both compounds interplanar lattice spacings increased after irradiation. Second, peak broadening possibly suggests incredibly small grain due to irradiation. Third, experiment results revealed an amorphization in the irradiated Sr3Ti2O7, while no amorphization was observed in irradiated SrTiO3. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Slow heavy ions inevitably produce a significant concentration of defects and lattice disorder in solids during their slowing-down process via ion-solid interactions. For irradiation effects research and many industrial applications, atomic defect production, ion range, and doping concentration are commonly estimated by the stopping and range of ions in matter (SRIM) code. In this study, ion-induced damage and projectile ranges of low energy Au ions in SiC are determined using complementary ion beam and microscopy techniques. Considerable errors in both disorder profile and ion range predicted by the SRIM code indicate an overestimation of the electronic stopping power, by a factor of 2 in most cases, in the energy region up to 25 keV/nucleon. Such large discrepancies are also observed for slow heavy ions, including Pt, Au, and Pb ions, in other compound materials, such as GaN, AlN, and SrTiO3. Due to the importance of these materials for advanced device and nuclear applications, better electronic stopping cross section predictions, based on a reciprocity principle developed by Sigmund, is suggested with fitting parameters for possible improvement.
