The development of green, renewable energy conversion and storage systems is an urgent task to address the energy crisis and environmental issues in the future. To achieve high performance, stable, and safe operation of energy conversion and storage systems, energy materials need to be modified and fabricated through rationalization. Among various modification and fabrication strategies, ion beam technology has been widely used to introduce various defects/ dopants into energy materials and fabricate various nanostructures, where the structure, composition, and property of prefabricated materials can be further accurately tailored to achieve better performance. In this paper, we review the recent progress in the application of ion beam technology in material modification and fabrication, focusing on nanostructured energy materials for energy conversion and storage including photo-(electro-) water splitting, batteries (solar cells, fuel cells, and metal-ion batteries), supercapacitors, thermoelectrics, and hydrogen storage. This review first provides a brief basic overview of ion beam technology and describes the classification and technological advantages of ion beam technology in the modification and fabrication of materials. Then, modification of energy materials by ion beams is reviewed mainly concerning doping and defect introduction. Fabrication of energy materials is also discussed mainly in terms of heterojunctions, nanoparticles, nanocavities, and other nanostructures. In particular, we emphasize the advantages of ion beam technology in improving the performance of energy materials. Finally, we point out our understanding of challenges and future perspectives in applying ion beam technology for the modification and fabrication of energy materials.

“…In the past decades, nanostructures have been the subject of interest in science and technology thanks to the size-dependent properties being different from their bulk counterparts [1][2][3]. In addition to bottom-up or top-down approaches to synthesize nanoscale materials, ion irradiation has been established as a powerful technique to fabricate and tune their properties for a wide variety of applications [4][5][6][7][8][9]. Whereas the understanding of ion-solid interaction processes in bulk and thin film materials has been developed to an advanced stage [5,10,11], ion-induced processes, effects and reactions strongly differ when nanoscale materials are involved, and the associated understanding requires significant adjustments [7,[12][13][14].…”

The disappearance and return of nanoparticles upon low energy ion irradiation

Ion irradiation of bulk and thin film materials is tightly connected to well described effects such as sputtering or/and ion beam mixing. However, when a nanoparticle is ion irradiated and the ion range is comparable to the nanoparticle size, these effects are to be reconsidered essentially. This study investigates the morphology changes of silver nanoparticles on top of silicon substrates, being irradiated with Ga+ ions in an energy range from 1 to 30 keV. The hemispherical shaped nanoparticles become conical due to an enhanced and curvature-dependent sputtering, before they finally disappear. The sputter yield and morphology changes can be well described by 3D Monte Carlo TRI3DYN simulations. However, the combination of sputtering, ion beam mixing, ion beam induced diffusion, and Ostwald ripening at ion energies lower than 8 keV results in the reappearance of new particles. These newly formed nanoparticles appear in various structures depending on the material and ion energy.

“…Surface nanostructures are created during the irradiation of thin films by the ion beam, whereas NS implanted in the substrate are created via recoil implantation. 25,26 By adjusting the ion beam parameters (energy, fluence, and angle of incidence) and the thickness of thin films, recoil implantation can be used to create specific nanostructures. In any of these scenarios, it is always useful to be aware of the ion beam characteristics as well as the depth distribution of the recoiling atoms as a function of the layer thickness.…”

SERS Detection of Rhodamine-6G on Ion Beam Nanostructured Ultra-Thin Gold (Au) Films: A Correlation between Fractal Growth, Water Contact-Angle and Raman Intensity

Surface enhanced Raman scattering (SERS) detection of rhodamine-6G on gold nanostructures (Au-NS) of various sizes under ion beam irradiation is presented. On a glass substrate, Au thin films of different thicknesses (~2, 3, and 5 nm) were deposited by thermal evaporation. Subsequent irradiation using 10 keV Ar+ at different fluences has been able to modify the size of Au-NS. Ion beam-induced sputtering and diffusion processes control the formation of Au-NS. The reduction in Au content during ion beam sputtering is confirmed by Rutherford backscattering spectroscopy, which also validates tuning the size and structures of Au-NS. The wettable characteristics of Au-NS surfaces are controlled by two competing statistical factors of sputtering and surface diffusion. A correlation between the water contact angle, rms roughness, and the detection of rhodamine-6G (R6G) by SERS is presented. The current study sheds light on the mechanism(s) of SERS chemical detection for wider metallic surfaces.
