Quantitative Analysis of Composition and Contamination of Atomically Thin Materials by Recoil-Projectile Coincidence in Ion Transmission
Carolin Frank, Kevin Vomschee, Tuan Thien Tran +6
Surface contamination strongly affects the intrinsic properties of nanoscale materials, making its reliable identification and quantification crucial for both accurate experimental…
Impurity atom configurations in diamond and their visibility via scanning transmission electron microscopy imaging
D. Propst, J. Kotakoski, E. H. Åhlgren
Dispersed impurities in diamond present a flourishing platform for research in quantum informatics, spintronics and single phonon emitters. Based on the vast pool of experimental a…
Two-dimensional few-atom noble gas clusters in a graphene sandwich
Manuel Längle, Kenichiro Mizohata, Clemens Mangler +4
Van der Waals atomic solids of noble gases on metals at cryogenic temperatures were the first experimental examples of two-dimensional systems. Recently such structures have also b…
Atomic-scale Oxygen-mediated Etching of 2D MoS and MoTe
E. Harriet Åhlgren, Alexander Markevich, Sophie Scharinger +6
Some of the materials are more affected by oxidation than others. To elucidate the oxidation-induced degradation mechanisms in transition metal chalcogenides, the chemical effects…
Xe Irradiation of Graphene on Ir(111): From Trapping to Blistering
Charlotte Herbig, E. Harriet Åhlgren, Ulrike A. Schröder +6
Using X-ray photoelectron spectroscopy, thermal desorption spectroscopy, and scanning tunneling microscopy we show that upon keV Xe + irradiation of graphene on Ir(111), Xe atoms a…
Structural manipulation of the graphene/metal-interface with Ar+ irradiation
E. H. Åhlgren, S. K. Hämäläinen, O. Lehtinen +2
Controlled defect creation is a prerequisite for the detailed study of disorder effects in materials. Here, we irradiate a graphene/Ir(111)-interface with low-energy Ar+ to study t…
Ion irradiation tolerance of graphene as studied by atomistic simulations
E. H. Åhlgren, J. Kotakoski, O. Lehtinen +1
As impermeable to gas molecules and at the same time transparent to high-energy ions, graphene has been suggested as a window material for separating a high-vacuum ion beam system…
Atomistic simulations of the implantation of low energy boron and nitrogen ions into graphene
E. H. Åhlgren, J. Kotakoski, A. V. Krasheninnikov
By combining classical molecular dynamics simulations and density functional theory total energy calculations, we study the possibility of doping graphene with B/N atoms using low-…
