“…The produced voids are potential precursors of the formation of a macroscopic sponge-like porosity observed under high fluence irradiations [342]. In diamond-like carbon, SHIs trigger atomic rearrangements that lead to graphitization, increased electrical conductivity, and a significant reduction in sp 3 bonds within the track [53,325,343,344]. This disordered phase along the track has a lower density which gradually increases from the track core outward until it reaches the value of the undamaged surrounding bulk material (Error!…”

This review concentrates on the specific properties and characteristics of damage structures generated with high-energy ions in the electronic energy loss regime. Irradiation experiments with so-called swift heavy ions (SHI) find applications in many different fields, with examples presented in ion-track nanotechnology, radiation hardness analysis of functional materials, and laboratory tests of cosmic radiation. The basics of the SHI-solid interaction are described with special attention to processes in the electronic subsystem. The broad spectrum of damage phenomena is exemplified for various materials and material classes, along with a description of typical characterization techniques. The review also presents state-of-the-art modeling efforts that try to account for the complexity of the coupled processes of the electronic and atomic subsystems. Finally, the relevance of SHI phenomena for effects induced by fission fragments in nuclear fuels and how this knowledge can be applied to better estimate damage risks in nuclear materials is discussed.

“…[17][18][19][20][21] High energy ion beam irradiation has been used to produce arrayed C-nanostructures within polymer, diamond-like carbon (DLC) and fullerene thin films [22][23][24] which have been characterised by ESR, Raman spectroscopy and electron transport measurements. 22,23,[25][26][27] Amorphous C-nanostructures within irradiated DLC have been shown to exhibit field emission properties. 27 We have employed ion beam irradiation to synthesize C-clusters within high aspect ratio nanochannel arrays having diameters of 15-25 nm in polymer media 24,28 which act as nanowires being very high aspect ratio structures L/D 600 with electronic behaviour different from its surrounding medium.…”

Thin polycarbonate films were spin-coated on silicon substrates and subsequently irradiated with 1-GeV U ions. The ion tracks in the polymer layer were chemically etched yielding nanopores of about 40 nm diameter. In a second process, the nanoporous polymer film acted as mask for structuring the Si substrate underneath. Sputtering with 5-keV Xe ions produced surface craters of depth ~150 nm and diameter ~70 nm. This arrangement can be used for the fabrication of track-based nanostructures with self-aligned apertures.
