ANT:UI: An interactive 3D tool for preparing ANT.Gaussian molecular junction geometries
A. Martinez-Garcia, J. J. Palacios, C. Sabater
ANT.UI is a Python graphical interface that automates the construction of molecular-junction geometries for NEGF-DFT quantum transport calculations. Through a real-time 3D viewer,…
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…
Stretching helical molecular springs: the peculiar evolution of electron transport in helicene junctions
Anil Kumar Singh, Yuta Ito, León Martin +10
Single-molecule junctions represent electromechanical systems at the edge of device miniaturization. Despite extensive studies on the interplay between mechanical manipulation and…
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…
Exploring Three-Atom-Thick Gold Structures as a Benchmark for Atomic-Scale Calibration of Break-Junction Systems
J. P. Cuenca, T. de Ara, A. Martinez-Garcia +2
We present an in-depth study of electronic transport in atomic-sized gold contacts using Break-Junction (BJ) techniques under cryogenic and ambient conditions. Our experimental res…
Conductance of atomic size contacts of Ag and Au at high magnetic fields
Beilun Wu, Andrés Martínez, Paula Obladen +6
Electronic conduction at the atomic scale can be described by Landauer's formalism. In single atom point contacts of noble metals like Au and Ag, there is just one channel open bet…
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…
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…
