“…391 It was found that both the irradiation dose and temperature greatly affect the welding of the MWNTs. At the irradiation dose of 5 ϫ 10 16 Si ions/ cm 2 , the formed MWNT junctions had well-ordered structure at the temperature range of 600-850 K. This work gives another confirmation that ion irradiation technology combined with heating can be used for interconnecting nanotubes in future nanodevices.…”

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.

“…With more efficient electron transfer and a more robust structure, a tailored 3D carbon will provide potentially higher electrochemical energy conversion by connecting the building blocks covalently instead of by van der Waals interactions. For example, CNTs have been welded together by ion beam irradiation at elevated temperatures . A graphene foam with a SSA of ≈850 m 2 g −1 that was prepared by chemical vapor deposition of carbon on a nickel foam has shown an excellent electrical and mechanical characteristics for Li‐ion batteries …”

Carbon nanotubes (CNTs) have attracted considerable attention due to their high aspect ratio, whisker-like form for best possible geometrical field enhancement, high electrical conductivity, and extraordinary thermal stability. Ion beam technology is a potential technique for controlled construction of CNTs. During collision with energetic ions, carbon atom of CNTs can get an adequate amount of energy to escape from the graphite lattice and produce a large number of defects. These defects are advantageous for adding some new functional groups and nanoparticles to modify CNTs. Meanwhile, the structure and atoms in the region of the defects can be rearranged and changed into amorphous structure, onion structure, and so on. These defects also can be used to form the junctions of CNTs and realize welding of CNTs and network formation of amorphous carbon nanowires.
