We experimentally discovered that Al2O3 and MgO exhibit well-pronouncednanometric modifications on the surfaces when irradiated under grazingincidence with 23 MeV I beam, in contrast to normal incidence irradiation withthe same ion beam when no damage was found. Moreover, ions in these twomaterials produce notably different structures: grooves surrounded withnanohillocks on MgO surfaces vs. smoother, roll-like discontinuous structureson the surfaces of Al2O3. To explain these results, detailed numericalsimulations were performed. We identified that a presence of the surfaceinhibits recrystallization process, thereby preventing transient tracks fromrecovery, and thus forming observable nanopatterns. Furthermore, a differencein the viscosities in molten states in Al2O3 vs. MgO explains the differencesin the created nanostructures. Our results thus provide a deeper understandingof the fundamental processes of surface nanostructuring, potentially allowingfor controlled production of periodic surface nanopatterns.
