Unraveling the Interplay between Quantum Transport and Geometrical Conformations in Monocyclic Hydrocarbons Molecular Junctions
A. Martinez-Garcia, T. de Ara, L. Pastor-Amat +4
In the field of molecular electronics, particularly in quantum transport studies, the orientation of molecules plays a crucial role. This orientation, with respect to the electrode…
Simulation of the Einstein-de Haas effect combining molecular and spin dynamics
W. Dednam, C. Sabater, A. E. Botha +3
The spin and lattice dynamics of a ferromagnetic nanoparticle are studied via molecular dynamics and with semi-classical spin dynamics simulations where spin and lattice degrees of…
Dynamic bonding influenced by the proximity of adatoms to one-atom high step edges
W. Dednam, S. Tewari, E. B. Lombardi +3
Low-temperature scanning tunneling microscopy is used here to study dynamic bonding of gold atoms on surfaces under low coordination conditions. In the experiments, using an atomic…
Unveiling the Signature of Adsorbed Organic Solvents for Molecular Electronics through STM Approaches
Tamara de Ara, Carlos Sabater, Carla Borja-Espinosa +4
After evaporation of the organic solvents, benzene, toluene, and cyclohexane on gold substrates, Scanning Tunneling Microscope (STM) shows the presence of a remaining adsorbed laye…
Raman Signal Reveals the Rhombohedral Crystallographic Structure in Ultra-thin Layers of Bismuth Thermally Evaporated on Amorphous Substrate
Carlos Rodríguez-Fernández, Kim Akius, Mauricio Morais de Lima +3
Under the challenge of growing a single bilayer of Bi oriented in the (111) crystallographic direction over amorphous substrates, we have studied different thicknesses of Bi therma…
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…
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…
Fast and accurate shot noise measurements on atomic-size junctions in the MHz regime
Sumit Tewari, Carlos Sabater, Manohar Kumar +3
Shot noise measurements on atomic and molecular junctions provide rich information about the quantum transport properties of the junctions and on the inelastic scattering events ta…
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…
Topologically protected quantum transport in locally exfoliated bismuth at room temperature
C. Sabater, D. Gosálbez-Martínez, J. Fernández-Rossier +3
We report electrical conductance measurements of Bi nanocontacts created by repeated tip-surface indentation using a scanning tunneling microscope at temperatures of 4 K and 300 K.…
Mechanical annealing of metallic electrodes at the atomic scale
C. Sabater, C. Untiedt, J. J. Palacios +1
The process of creating an atomically defined and robust metallic tip is described and quantified using measurements of contact conductance between gold electrodes and numerical si…
