Data for "Charge-exchange-dependent energy loss of H and He in freestanding monolayers of graphene and MoS2"

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 "Charge-exchange-dependent energy loss of H and He in freestanding  monolayers of graphene and MoS2". 

Context and methodology

• Energy distributions of H and He ions are measured after transmission through 2D materials (freestanding monolayers of graphene and MoS2). An electrostatic analyser is used for particles that remained charged during the interaction; a time-of-flight approach for neutralised particles. Additional time-dependent density functional theory calculations are performed to compare to experimental data.
• The data consists of several ASCII data sets, wich are all included within the uploaded files. For experiments, the data includes measured count rates for a given parameter (time of flight or energy change) and extracted mean values of the obtained distributions. For the simulations, the data includes the determined energy change for the given simulation parameters (sample, particle species, energy).

Technical details

• The dataset includes two analysis files in .dgraph-format (see below). Figures 2-5 (excluding schematics) are prepared using one file named according to the figure numbers; Figure 6 is obtained through the second file (also named _FIG6). The data inside the files is sturctured in a folder-tree labelled according to the content of the figure and/or the number of the final figure.
• DataGraph from Visual Data Tools is required to open this data set. The data was created using version 5.5.2beta.
