Ion tracks in silicon formed by much lower energy deposition than the track formation threshold [PDF]
Scientific Reports, 2021 Damaged regions of cylindrical shapes called ion tracks, typically in nano-meters wide and tens micro-meters long, are formed along the ion trajectories in many insulators, when high energy ions in the electronic stopping regime are injected.

Latent ion tracks were finally observed in diamond [PDF]
Nature CommunicationsInjecting high-energy heavy ions in the electronic stopping regime into solids can create cylindrical damage zones called latent ion tracks. Although these tracks form in many materials, none have ever been observed in diamond, even when irradiated with ...

Comprehensive Understanding of Hillocks and Ion Tracks in Ceramics Irradiated with Swift Heavy Ions
Quantum Beam Science, 2020 Amorphizable ceramics (LiNbO3, ZrSiO4, and Gd3Ga5O12) were irradiated with 200 MeV Au ions at an oblique incidence angle, and the as-irradiated samples were observed by transmission electron microscopy (TEM).

Base-excision repair increases DNA double-strand break clustering within heavy-ion tracks and modulates repair at δ-electron-induced breaks [PDF]
Scientific ReportsSpace radiation poses a threat to human health during space missions. Its biological effect largely depends on heavy ions. These induce highly clustered DNA damage along their tracks, which is difficult to repair. If this damage is not repaired correctly,

Helium Ions Put Magnetic Skyrmions on the Track [PDF]
Nano Letters, 2021 Magnetic skyrmions are deemed to be the forerunners of novel spintronic memory and logic devices. While their observation and their current-driven motion at room temperature have been demonstrated, certain issues regarding their nucleation, stability, pinning, and skyrmion Hall effect still need to be overcome to realize functional devices.
