“…As an explanation for this behaviour one typically uses charge mobilities in the respective materials: While in metals the deposited energy can be dissipated very fast, in semiconductors and insulators a confinement of the energy around the impact position leads to a translation of the excitation energy to the lattice system and further on to the formation of nanostructures. Only recently, experiments with gold nanoislands [60] and nanolayers [112] could demonstrate that in these limited volumes material modifications induced by HCI impact becomes possible.…”

Electron beam ion traps allow studies of slow highly charged ion transmission through freestanding 2D materials as an universal testbed for surface science under extreme conditions. Here we review recent studies on charge exchange of highly charged ions in 2D materials. Since the interaction time with these atomically thin materials is limited to only a few femtoseconds, an indirect timing information will be gained. We will therefore discuss the interaction separated in three participating time regimes: energy deposition (charge exchange), energy release (secondary particle emission), and energy retention (material modification).

“…The research conducted by our group focuses on studying the processes of forming surface nanostructures in the interaction of highly charged xenon ions with nanolayers using the Kielce EBIS facility of the Jan Kochanowski University (Kielce, Poland) [16]. Research centers on metallic (Au, Ti) nanolayers [15,17] as well as the dependence of nanostructure sizes on the kinetic and potential energy of the Xe ions. In order to continue the study for other metallic nanolayers (with different thickness values) and to interpret the results correctly, it is necessary to know the properties of the nanolayers obtained by applying X-ray photoelectron spectroscopy with the best possible detection limit.…”

In the presented study, X-ray photoelectron spectroscopy and total reflection X-ray photoelectron spectroscopy methods were applied to analyze the Ti (75 nm) and Pd (100 nm) nanolayers deposited on the Si substrate using magnetron sputtering. The aim of the research was to determine the elemental composition and surface homogeneity of the analyzed nanolayers before their irradiation with highly charged xenon ions and to estimate the detection limit of the X-ray photoelectron spectroscopy technique for various glancing angles. The measurements were conducted using the SPECS mono-XPS system in the Institute of Physics at the Jan Kochanowski University (Kielce, Poland). The experimental setup and measurement conditions for the studied Ti and Pd layers are described. The X-ray photoelectron spectroscopy spectra were registered both for the non-total (35 • and 10 • angles) and total reflection (2.2 • for the Pd nanolayer and 1.5 • for the Ti nanolayer) regimes. The position of the C 1s photoelectron peak was applied (C-C component, binding energy 284.8 eV) to calibrate energy. First, the homogeneity of the nanolayers was investigated. The analysis of spectra concentrated on investigating the photoelectron peaks and, consequently, on determining the following: the binding energy of electrons, the intensity and full width at half maximum of photoelectron peaks, the background level, and the elemental composition of the nanolayer surface. In this study, the detection limit of the X-ray photoelectron spectroscopy measurements for different photoelectron peaks was calculated in relation to the excitation angle. An improvement of the X-ray photoelectron spectroscopy detection limit by a factor of 3-6, depending on the type of photoelectron peak, was observed for the angles below the critical angle of the X-ray total reflection phenomenon. topics: Ti and Pd nanolayers, X-ray photoelectron spectroscopy (XPS), total reflection XPS
