Cross section TEM bright field images of irradiated single crystals of YSZ, MgAl2O4 and Al2O3 from top surface to irradiated interior with Stopping and Range of Ions in Matter (SRIM) calculation29. SRIM calculations predict that the damage peak lies at ~1.6 μm from the irradiated surface and the damage depth is ~2 μm. Even though MgAl2O4 is known to be sensitive to ionizing and displacive irradiation spectra, only a small amount of dislocation loops was observed in this study. This must be due to ionizing radiation effect with high electronic to nuclear stopping power ratio whose influence becomes more significant for light elements18.
