    • Angle-dependent charge exchange and energy loss of slow highly charged ions in freestanding graphene 

      Creutzburg, Sascha; Niggas, Anna; Weichselbaum, David; Grande, Pedro Luis; Aumayr, Friedrich; Wilhelm, Richard Arthur (2021) [Artigo de periódico]
      The scattering of ions in solids is accompanied with momentum transfer and electronic excitations resulting in the slowing down of the ion. The amount of energy transferred in a single scattering event depends on the ...

    • Peeling graphite layer by layer reveals the charge exchange dynamics of ions inside a solid 

      Niggas, Anna; Creutzburg, Sascha; Schwestka, Janine; Wöckinger, Benjamin; Gupta, Tushar; Grande, Pedro Luis; Eder, Dominik; Marques, José Pires; Bayer, Bernhard C.; Aumayr, Friedrich; Bennett, R.; Wilhelm, Richard Arthur (2021) [Artigo de periódico]
      Over seventy years ago, Niels Bohr described how the charge state of an atomic ion moving through a solid changes dynamically as a result of electron capture and loss processes, eventually resulting in an equilibrium charge ...

    • Vanishing influence of the band gap on the charge exchange of slow highly charged ions in freestanding single-layer MoS2 

      Creutzburg, Sascha; Schwestka, Janine; Niggas, Anna; Inani, Heena; Tripathi, Mukesh; George, Antony; Heller, René; Kozubek, Roland; Madauß, Lukas; McEvoy, Niall; Facsko, Stefan; Kotakoski, Jani; Schleberger, M.; Turchanin, Andrey; Grande, Pedro Luis; Aumayr, Friedrich; Wilhelm, Richard Arthur (2020) [Artigo de periódico]
      Charge exchange and kinetic energy loss of slow highly charged xenon ions transmitted through freestanding monolayer MoS2 are studied. Two distinct exit charge state distributions, characterized by high and low charge ...
