Graphene on insulating crystalline substrates
S. Akcoeltekin, M. El Kharrazi, B. Koehler +2
We show that it is possible to prepare and identify ultra--thin sheets of graphene on crystalline substrates such as SrTiO, TiO, AlO and CaF by standard techniq…
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…
HICS: Highly charged ion collisions with surfaces
Thorsten Peters, Christian Haake, Johannes Hopster +3
The layout of a new instrument designed to study the interaction of highly charged ions with surfaces, which consists of an ion source, a beamline including charge separation and a…
Distance dependence of the phase signal in eddy current microscopy
Tino Roll, Marion Meier, Ulrich Fischer +1
Atomic force microscopy using a magnetic tip is a promising tool for investigating conductivity on the nano-scale. By the oscillating magnetic tip eddy currents are induced in the…
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…
