Review of Swift Heavy Ion Irradiation Effects in CeO₂ [PDF]

Quantum Beam Science, 2021
Cerium dioxide (CeO2) exhibits complex behavior when irradiated with swift heavy ions. Modifications to this material originate from the production of atomic-scale defects, which accumulate and induce changes to the microstructure, chemistry, and ...

High-Energy Heavy Ion Tracks in Nanocrystalline Silicon Nitride

Crystals, 2022
At present, silicon nitride is the only nitride ceramic in which latent ion tracks resulting from swift heavy ion irradiation have been observed. Data related to the effects of SHIs on the nanocrystalline form of Si3N4 are sparse.

Amorphization of Ta2O5 under swift heavy ion irradiation

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2017
Abstract Crystalline Ta 2 O 5 powder is shown to amorphize under 2.2 GeV 197 Au ion irradiation. Synchrotron X-ray diffraction (XRD), Raman spectroscopy, small-angle X-ray scattering (SAXS), and transmission electron microscopy (TEM) were used to characterize the structural transition from crystalline to fully-amorphous.
