Electrostatic forces above graphene nanoribbons and edges interpreted as partly hydrogen-free
Sebastian Schneider, Regina Hoffmann-Vogel
Graphene nanoribbons' electronic transport properties strongly depend on the type of edge, armchair, zigzag or other, and on edge functionalization that can be used for band-gap en…
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.…
Film thickness of Pb islands on the Si(111) surface
Th. Späth, M. Popp, R. Hoffmann-Vogel
We analyze topographic scanning force microscopy images together with Kelvin probe images obtained on Pb islands and on the wetting layer on Si(111) for variable annealing times. W…
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…
