Benchmarking Current-to-Voltage Amplifiers for Quantum Transport Measurements
J. Escorza, G. Pellicer, T. de Ara +4
Accurate electrical amplification is essential in molecular electronics for measuring conductance through atomic and molecular junctions, where currents often span several orders o…
Measurement of the Quantum Capacitance Between Two Metallic Electrodes
T. de Ara, B. Olivera, C. Sabater +1
Two factors contribute to the electrical capacitance between two electrodes: a classical contribution, stemming from the electric field, and a quantum contribution, governed by the…
Evidence of an Off-resonant Electronic Transport Mechanism in Helicenes
T. de Ara, C. Hsu, A. Martinez-Garcia +9
Helical molecules have been identified as potential candidates for investigating electronic transport, spin filtering, or even piezoelectricity. However, the description of the tra…
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…
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…
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…
