Structure and local charging of electromigrated Au nanocontacts
Daniel Arnold, Michael Marz, Sebastian Schneider +1
We study the structure and the electronic properties of Au nanocontacts created by controlled electromigration of thin film devices, a method frequently used to contact molecules.…
Epitaxial growth of C on highly oriented pyrolytic graphite surfaces studied at low temperatures
E. Seydel, R. Hoffmann-Vogel, M. Marz
Graphite surfaces interact weakly with molecules compared to other conducting surfaces bringing the molecule-molecule interaction to the foreground. C on highly oriented pyr…
Near-equilibrium measurement of quantum size effects using Kelvin probe force microscopy
Thomas Späth, Matthias Popp, Carmen Pérez León +2
In nano-structures such as thin films electron confinement results in the quantization of energy levels in the direction perpendicular to the film. The discretization of the energy…
Atomically resolved scanning force studies of vicinal Si(111)
Carmen Perez Leon, Holger Drees, Stefan Martin Wippermann +2
Well-ordered stepped semiconductor surfaces attract intense attention owing to the regular arrangements of their atomic steps that makes them perfect templates for the growth of on…
Atomic-scale imaging of the surface dipole distribution of stepped surfaces
Carmen P érez León, Holger Drees, Stefan Martin Wippermann +2
Stepped well-ordered semiconductor surfaces are important as nanotemplates for the fabrication of one-dimensional nanostructures which are candidates of intriguing electronic prope…
Unusual resistance-voltage dependence of nanojunctions during electromigration in ultra-high vacuum
D. Stöffler, M. Marz, B. Kießig +4
The electrical resistance R of metallic nanocontacts subjected to controlled cyclic electromigration in ultra-high vacuum has been investigated in-situ as a function of applied vol…
Andreev experiments on superconductor/ferromagnet point contacts
S. Bouvron, M. Stokmaier, M. Marz +1
Andreev reflection is a smart tool to investigate the spin polarisation P of the current through point contacts between a superconductor and a ferromagnet. We compare different mod…
