“…In particular, the global roughness exponent of the film indicates the vertical growth as a function of their lateral growths, which is measured using the mathematical equation w ∼ ξ ζ . 19 In the present case, the global roughness exponent value is found to be ζ = 0.96 ± 0.08. The value of ζ ≃ 1 suggests an equal amount of vertical and lateral growth of the nanostructures.…”

“…These parameters are evaluated under the framework of scaling theory in order to confirm whether a surface is self-affine 17,18 or mounded. 19 The surface of a thin film produced by magnetron sputtering is often found to be self-affine, and it typically shows fractal characteristics. Fractal analyses of a thin film surface have been performed to understand the topographical complexities and randomness of the films during their growth, which is basically measured in terms of fractal dimensions (FDs).…”

Surface morphology and wetting property of silver nanocluster-deposited films have been comprehensively investigated. A gas aggregation-type magnetron sputtering process is used to produce Ag nanoclusters, and the films are prepared by varying the cluster ion currents. The morphological result suggests that the deposited clusters agglomerate over the surface and also the overall size distribution is affected with increasing ion current. The morphological data are used to characterize various statistical parameters of the surface such as the interface width, autocorrelation function, power spectral density function, and fractal dimensions of the films. The X-ray photoelectron spectroscopy study reveals that the produced Ag nanostructures are made of pure metallic silver, and the total atomic concentration of silver on the surface increases with the increase of cluster ion currents. Wettability study of the films reveals that the morphological parameters along with the changing surface chemistry influenced the wetting property of the films. A sudden transition in surface wettability from hydrophilic to hydrophobic is observed for the films measured via water contact angle measurements. The comparison with the theoretical values suggests that the nanostructures produced for higher ion currents follow the Wenzel’s model. Finally, a correlation between the fractal dimension and the water contact angle values has been observed.

Surface nanopatterning induced by ion beam irradiation (IBI) has emerged as an effective nanostructuring technique since it induces patterns on large areas of a wide variety of materials, in short time, and at low cost. Nowadays, two main subfields can be distinguished within IBI nanopatterning depending on the irrelevant or relevant role played by the surface composition. In this review, we give an up-dated account of the progress reached when surface composition plays a relevant role, with a main focus on IBI surface patterning with simultaneous co-deposition of foreign atoms. In addition, we also review the advances in IBI of compound surfaces as well as IBI systems where the ion employed is not a noble gas species. In particular, for the IBI with concurrent metal co-deposition, we detail the chronological evolution of these studies because it helps us to clarify some contradictory early reports. We describe the main patterns obtained with this technique as a function of the foreign atom deposition pathway, also focusing in those systematic studies that have contributed to identify the main mechanisms leading to the surface pattern formation and development. Likewise, we explain the main theoretical models aimed at describing these nanopattern formation processes. Finally, we address two main special features of the patterns induced by this technique, namely, the enhanced pattern ordering and the possibility to produce both morphological and chemical patterns.
