Observation of electronic and atomic shell effects in gold nanowires
A. I. Mares, A. F. Otte, L. G. Soukiassian +2
The formation of gold nanowires in vacuum at room temperature reveals a periodic spectrum of exceptionally stable diameters. This is identified as shell structure similar to that w…
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…
Observation of a parity oscillation in the conductance of atomic wires
R. H. M. Smit, C. Untiedt, G. Rubio-Bollinger +2
Using a scanning tunnel microscope or mechanically controlled break junctions, atomic contacts of Au, Pt and Ir are pulled to form chains of atoms. We have recorded traces of condu…
Conductance of single-atom platinum contacts: Voltage-dependence of the conductance histogram
S. K. Nielsen, Y. Noat, M. Brandbyge +6
The conductance of a single-atom contact is sensitive to the coupling of this contact atom to the atoms in the leads. Notably for the transition metals this gives rise to a conside…
