Manipulation of the graphene surface potential by ion irradiation
O. Ochedowski, B. Kleine Bussmann, B. Ban d'Etat +2
We show that the work function of exfoliated single layer graphene can be modified by irradiation with swift (E_{kin}=92 MeV) heavy ions under glancing angles of incidence. Upon io…
Damage in graphene due to electronic excitation induced by highly charged ions
J. Hopster, R. Kozubek, B. Ban-d'Etat +3
Graphene is expected to be rather insensitive to ionizing particle radiation. We demonstrate that single layers of exfoliated graphene sustain significant damage from irradiation w…
New experimental setup for in situ measurement of slow ion induced sputtering
P. Salou, H. Lebius, A. Benyagoub +3
A new experimental equipment allowing to study the sputtering induced by ion beam irradiation is presented. The sputtered particles are collected on a catcher which is analyzed in…

E. Gardés, E. Balanzat, B. Ban-d'Etat +8
We developed a new sub-nanosecond time-resolved instrument to study the dynamics of UV-visible luminescence under high stopping power heavy ion irradiation. We applied our instrume…
Unzipping graphene: Extendend defects by ion irradiation
S. Akcöltekin, H. Bukowska, T. Peters +6
Many of the proposed future applications of graphene require the controlled introduction of defects into its perfect lattice. Energetic ions provide one way of achieving this chall…
Detecting swift heavy ion irradiation effects with graphene

In this paper we show how single layer graphene can be utilized to study swift heavy ion (SHI) modifications on various substrates. The samples were prepared by mechanical exfoliat…
Substrate-dependent pore formation in molybdenum disulfide monolayers under ion irradiation
Y. Liebsch, U. Javed, L. Skopinski +11
Ion irradiation is a versatile tool for nanostructuring surfaces, yet the roles of energy deposition and dissipation at the surface and in ultrathin materials remain poorly underst…
