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…
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…
Hot electrons induced by (rather) cold ions
Thorsten Peters, Christian Haake, Detlef Diesing +6
Thin film metal-insulator-metal junctions are used in a novel approach to investigate the dissipation of potential energy of multiply charged ions impinging on a polycrystalline me…
