Mass transport via in-plane nanopores in graphene oxide membranes
Tobias Foller, Lukas Madauss, Dali Ji +8
Angstrom confined solvents in two-dimensional laminates travel through interlayer spacings, gaps between adjacent sheets, and via in plane pores. Among these, experimental access t…
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…
Online in-situ X-ray diffraction setup for structural modification studies during swift heavy ion irradiation
C. Grygiel, H. Lebius, S. Bouffard +8
The high energy density of electronic excitations due to the impact of swift heavy ions can induce structural modifications in materials. We present a X-ray diffractometer called A…
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…
Energy threshold for nanodot creation by swift heavy ions
Marko Karlusic, Sevilay Akcoeltekin, Orkhan Osmani +4
We present theoretical and experimental data on the threshold behaviour of nanodot creation with swift heavy ions. A model calculation based on a two-temperature model taking the s…
Swift heavy ion irradiation of SrTiO under grazing incidence
Ender Akcoeltekin, Sevilay Akcoeltekin, Orkhan Osmani +2
The irradiation of SrTiO single crystals with swift heavy ions leads to modifications of the surface. The details of the morphology of these modifications depends strongly on t…
Ab-initio calculation of electronic stopping power along glancing swift heavy ion tracks in perovskites
O. Osmani, A. Duvenbeck, E. Akcoeltekin +3
In recent experiments the irradiation of insulators of perovskite type with swift heavy ions under glancing incidence has been shown to provide a unique means to generate periodica…
Creation of multiple nanodots by single ions
Ender Akcöltekin, Thorsten Peters, Ralf Meyer +5
In the challenging search for tools that are able to modify surfaces on the nanometer scale, heavy ions with energies of several 10 MeV are becoming more and more attractive. In co…
