“…It is visible that unirradiated HOPG has smooth surface with corrugation in range of 100 pm within one terrace and that after irradiation HOPG has visible ion tracks that corrugate surface more than 500 pm. These tracks have a distinct discontinuous morphology [ 40 ], that is also observed in other materials [ 2 , 41 , 42 , 43 , 44 , 45 ] due to the locally varying electronic stopping power experienced by the SHI when passing through atomic layers at grazing incidence.…”

Both silicon and graphite are radiation hard materials with respect to swift heavy ions like fission fragments and cosmic rays. Recrystallisation is considered to be the main mechanism of prompt damage anneal in these two materials, resulting in negligible amounts of damage produced, even when exposed to high ion fluences. In this work we present evidence that these two materials could be susceptible to swift heavy ion irradiation effects even at low energies. In the case of silicon, ion channeling and electron microscopy measurements reveal significant recovery of pre-existing defects when exposed to a swift heavy ion beam. In the case of graphite, by using ion channeling, Raman spectroscopy and atomic force microscopy, we found that the surface of the material is more prone to irradiation damage than the bulk.

“…Another approach, investigated in this work, is to utilize the energy of the ion beams to introduce defects into the material and thus influence its properties. In this way, the location, morphology and amount of damage can be fine-tuned by changing ion irradiation parameters (like ion type, energy and fluence) [ 1 , 2 ].…”

“…Finally, we consider the use of energetic ion irradiations for materials modifications when ion irradiation is done at non-normal incidence angles, in particular at grazing angles. This type of irradiation has been found to be very efficient in nanostructuring surfaces, thin films and 2D materials [ 20 ]. Grazing incidence irradiation by energetic ions produces long ion tracks on the material surface [ 30 , 31 , 32 ], and in the case of the 2D materials, such irradiation produces pores [ 15 , 33 ].…”

“…Effects of the high energy ion irradiation on very thin targets and 2D materials such as graphene are in the focus of research [ 15 , 16 , 17 , 18 ]. Material removal from later stages of the ion track formation in thin targets can lead to diverse ion track morphologies [ 18 , 19 , 20 ]. However, even more importantly, escape of the deposited energy into the vacuum via electron emission should substantially affect ion track formation in thin targets and 2D materials [ 18 , 21 ].…”

Energy Retention in Thin Graphite Targets after Energetic Ion Impact

High energy ion irradiation is an important tool for nanoscale modification of materials. In the case of thin targets and 2D materials, which these energetic ions can pierce through, nanoscale modifications such as production of nanopores can open up pathways for new applications. However, materials modifications can be hindered because of subsequent energy release via electron emission. In this work, we follow energy dissipation after the impact of an energetic ion in thin graphite target using Geant4 code. Presented results show that significant amount of energy can be released from the target. Especially for thin targets and highest ion energies, almost 40% of deposited energy has been released. Therefore, retention of deposited energy can be significantly altered and this can profoundly affect ion track formation in thin targets. This finding could also have broader implications for radiation hardness of other nanomaterials such as nanowires and nanoparticles.

“…Ion irradiation parameters such as ion type, energy and fluence can be easily tuned to achieve the desired densities of defects at pre-defined depths [ 1 , 2 , 3 ]. Furthermore, high-energy heavy ion irradiation can also be used, with a great degree of control, to change material surfaces [ 4 , 5 , 6 ] and create nanomaterials [ 7 , 8 , 9 , 10 , 11 ]. These attractive possibilities stem from the fact that high-energy heavy ions travel through the material in almost straight lines.…”

High-Energy Heavy Ion Irradiation of Al2O3, MgO and CaF2

High-energy heavy ion irradiation can produce permanent damage in the target material if the density of deposited energy surpasses a material-dependent threshold value. It is known that this threshold can be lowered in the vicinity of the surface or in the presence of defects. In the present study, we established threshold values for Al2O3, MgO and CaF2 under the above-mentioned conditions, and found those values to be much lower than expected. By means of atomic force microscopy and Rutherford backscattering spectrometry in channelling mode, we present evidence that ion beams with values of 3 MeV O and 5 MeV Si, despite the low density of deposited energy along the ion trajectory, can modify the structure of investigated materials. The obtained results should be relevant for radiation hardness studies because, during high-energy ion irradiation, unexpected damage build-up can occur under similar conditions.
