Multiple Andreev reflection in single atom niobium junctions
B. Ludoph, N. van der Post, E. N. Bratus' +4
Single atom junctions between superconducting niobium leads are produced using the Mechanically Controllable Break Junction technique. The current-voltage characteristics of these…
Conductance fluctuations as a tool for investigating the quantum modes in atomic size metallic contacts
B. Ludoph, J. M. van Ruitenbeek
Recently it has been observed that the conductance fluctuations of atomic size gold contacts are suppressed when the conductance is equal to an integer multiple of the conductance…
Thermopower of atomic-size metallic contacts
B. Ludoph, J. M. van Ruitenbeek
The thermopower and conductance of atomic-size metallic contacts have been simultaneously measured using a mechanically controllable break junction. For contacts approaching atomic…
Evidence for saturation of channel transmission from conductance fluctuations in atomic-size point contacts
B. Ludoph, M. H. Devoret, D. Esteve +2
The conductance of atomic size contacts has a small, random, voltage dependent component analogous to conductance fluctuations observed in diffusive wires (UCF). A new effect is ob…
