“…126,598 With respect to nanostructures, the desorption of Au, Ag, Pt, In, Ge, UO 2 , and PbS nanocluster films by swift heavy ions has been studied. 599,600 For Au, nanodispersed films containing Au nanoclusters of different sizes were first manufactured on a surface by vapor deposition of gold on amorphous carbon at substrate temperatures of 20-400°C ͑see Fig. 83͒, Ref.…”

“…Moreover, the sputtered nanoclusters were more nearly spherical in shape than the initial ones, which suggests that they have been molten during the desorption process due to the energy deposition from the swift heavy ions. 599,600 At somewhat lower ion energies, films containing Au nanoclusters were irradiated with 100 MeV Au ions, and the size distribution of the sputtered material was measured. 601 Sputtering of up to 300 000 atom particles was reported, and the size distribution of the sputtered material was shown to be described well by a power law with two exponents.…”

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.

“…In addition to cluster emission during sputtering, in some specific experiments the emission of nanoparticles, which had been adsorbed to the surface of a substrate prior to bombardment, has been reported. In a series of experiments, Baranov and coworkers found that such emission occurs for a wide range of impact conditions; the most recent references include [17][18][19][20][21]. These authors investigated energy deposition by the projectile both in the nuclear stopping regime -for instance, impact of 72 keV Au 400 clusters or 200 keV Au 5 clusters -and in the electronic stopping regime, such as 1 GeV Pb ions or 30 MeV C 60 clusters.…”
