Data for "Peeling graphite layer by layer reveals the charge exchange dynamics of ions inside a solid"

Contents of this data set

This repository contains the processed experimental data as well as the evaluation procedure applied to create the figures published in "Peeling graphite layer by layer reveals the charge exchange dynamics of ions inside a solid". 

Context and methodology

• Highly charged ion neutralisation upon transmission through 2D materials is measured using the ion beam spectrometer at TU Wien. Data is recorded for the charge state evolution of the highly charged ions upon transmission through 1, 2 and 3 layers of graphene for different ion velocities and charge states. Thereby the duration of the ion neutralisation is indirectly approached.
• Experimental data is compared to a first-principles approach based on the virtual photon model for interparticle energy transfer. 
• For the supplementary data, charge exchange data acquired with the simulation package TDPot is used. 
• The data comprises experimentally determined mean exit charge states of highly charged xenon ions for (1) different irradiation parameters and 1, 2 or 3-layered materials and (2) different material layer numbers per ion irradiation parameter; TDPot simulation data and decay rates in dependence of the interatomic distance.

Technical details

• The dataset includes one file in .dgraph-format (see below). All manuscript figures (excluding schematics and microscopy data) can be reproduced using this data file. The data inside the file is structured in a folder-tree labelled according to the content of the figure and/or the final (sub) figure number.
• DataGraph from Visual Data Tools is required to open this data set. The data was created using version 5.5.2beta.
