Directional bonding explains high conductance values of atomic contacts in bcc metals
W. Dednam, C. Sabater, M. R. Calvo +4
Atomic-sized junctions of iron, created by controlled rupture, present unusually high values of conductance compared to other metals. This result is counter-intuitive since, at the…
Influence of relativistic effects on the contact formation of transition metals
M. R. Calvo, C. Sabater, W. Dednam +3
Our analysis of the contact formation processes undergone by Au, Ag and Cu nanojunctions, reveals that the distance at which the two closest atoms on a pair of opposing electrodes…
The role of first neighbors geometry in the electronic and mechanical properties of atomic contacts
C. Sabater, W. Dednam, M. R. Calvo +3
We study in detail, by experimental measurements, atomistic simulations and DFT transport calculations, the process of formation and the resulting electronic properties of atomic-s…
MMonCa: An Object Kinetic Monte Carlo simulator for damage irradiation evolution and defect diffusion
Ignacio Martin-Bragado, Antonio Rivera, Gonzalo Valles +2
In this work we introduce the Object Kinetic Monte Carlo (OKMC) simulator MMonCa and simulate the defect evolution in three different materials. We start by explaining the theory o…
Modeling contact formation between atomic-sized gold tips via molecular dynamics
W. Dednam, C. Sabater, M. A. Fernandez +3
The formation and rupture of atomic-sized contacts is modelled by means of molecular dynamics simulations. Such nano-contacts are realized in scanning tunnelling microscope and mec…
Understanding the structure of the first atomic contact in Gold
C. Sabater, M. J. Caturla, J. J. Palacios +1
We have studied experimentally the phenomena of jump-to-contact (JC) and jump-out-of-contact (JOC) in gold electrodes. JC can be observed at the first contact when the two metals a…
