“…Although the low-energy ͑eV or keV͒ incoming ions are quickly neutralized by capturing electrons from the target, 82 in what follows, the incoming ion or atom is always referred to as "ion" to differentiate between the projectile and recoil atoms. If the target recoil atom acquires kinetic energy enough to leave its position in the atomic network, various atomic-scale defects may appear in the target.…”

A common misconception is that the irradiation of solids with energetic electrons and ions has exclusively detrimental effects on the properties of target materials. In addition to the well-known cases of doping of bulk semiconductors and ion beam nitriding of steels, recent experiments show that irradiation can also have beneficial effects on nanostructured systems. Electron or ion beams may serve as tools to synthesize nanoclusters and nanowires, change their morphology in a controllable manner, and tailor their mechanical, electronic, and even magnetic properties. Harnessing irradiation as a tool for modifying material properties at the nanoscale requires having the full microscopic picture of defect production and annealing in nanotargets. In this article, we review recent progress in the understanding of effects of irradiation on various zero-dimensional and one-dimensional nanoscale systems, such as semiconductor and metal nanoclusters and nanowires, nanotubes, and fullerenes. We also consider the two-dimensional nanosystem graphene due to its similarity with carbon nanotubes. We dwell on both theoretical and experimental results and discuss at length not only the physics behind irradiation effects in nanostructures but also the technical applicability of irradiation for the engineering of nanosystems.

“…Studies of the interactions of slow (v < v Bohr ), highly charged ions (HCI) with solid surfaces were originally aimed at gaining an understanding of the dynamical processes governing neutralization, relaxation and eventual dissipation of the very high potential energy density (∼ keV/Å 3 ) within a few femtoseconds [1][2][3][4][5][6]. This potential energy carried into the collision is given by the sum of all binding energies of electrons missing.…”

“…The ion impact ionization cross-sections are large only for ultra-high energy ions, which are at present efficiently produced only in ion accelerators (Fortov, 2009). It is necessary to mention that the first observations of the spectra of hollow atoms were done in accelerator experiments (Briand et al, 1990). At the same time for laser-produced plasma such mechanism is not very important, because there are serious difficulties to produce ultra-high energy ions in this case.…”

Diagnostics of warm dense matter by high-resolution X-ray spectroscopy of hollow ions

The short review on the possible applications of the hollow ion spectra for the diagnostics of the high-temperature plasma created by intensive laser and particle beams is presented. Because of the hollow ion spectra features are defined mainly by the mechanisms of their excitation, we consider the various types of the high-temperature plasma where different excitation processes are important. It is shown that like ordinary spectral lines, spectra of the hollow ions offer considerable diagnostic opportunities. At the present time, hollow ion spectra are used mainly to investigate plasma heated by X-ray radiation, but the hollow ions must be generated when plasma is heated by fast heavy ion beams too. In this case, the resultant substance state will be also characterized by solid-state density, and some spatial regions of targets will have relatively low temperatures, i.e., will be a nonideal plasma. It is emphasized that hollow ion spectra are promising diagnostic tool for both nonideal plasma and warm dense matter.
