Electronic and atomic shell structure in aluminum nanowires
A. I. Mares, D. F. Urban, J. Bürki +3
We report experiments on aluminum nanowires in ultra-high vacuum at room temperature that reveal a periodic spectrum of exceptionally stable structures. Two "magic" series of stabl…
Formation of a Metallic Contact: Jump to Contact Revisited
C. Untiedt, M. J. Caturla, M. R. Calvo +3
The transition from tunneling to metallic contact between two surfaces does not always involve a jump, but can be smooth. We have observed that the configuration and material compo…
Vibrationally Induced Two-Level Systems in Single-Molecule Junctions
W. H. A. Thijssen, D. Djukic, A. F. Otte +2
Single-molecule junctions are found to show anomalous spikes in dI/dV spectra. The position in energy of the spikes are related to local vibration mode energies. A model of vibrati…
High-bias stability of monatomic chains
R. H. M. Smit, C. Untiedt, J. M. van Ruitenbeek
For the metals Au, Pt and Ir it is possible to form freely suspended monatomic chains between bulk electrodes. The atomic chains sustain very large current densities, but finally f…
