Thermoelectric Scanning Gate Interferometry on a Quantum Point Contact
B. Brun, F. Martins, S. Faniel +11
We introduce a new scanning probe technique derived from scanning gate microscopy (SGM) in order to investigate thermoelectric transport in two-dimensional semiconductor devices. T…
Electron phase shift at the zero-bias anomaly of quantum point contacts
B. Brun, F. Martins, S. Faniel +11
The Kondo effect is the many-body screening of a local spin by a cloud of electrons at very low temperature. It has been proposed as an explanation of the zero-bias anomaly in quan…
Wigner and Kondo physics in quantum point contacts revealed by scanning gate microscopy
B. Brun, F. Martins, S. Faniel +11
Quantum point contacts exhibit mysterious conductance anomalies in addition to well known conductance plateaus at multiples of 2e^2/h. These 0.7 and zero-bias anomalies have been i…
Single-dopant resonance in a single-electron transistor
V. N. Golovach, X. Jehl, M. Houzet +4
Single dopants in semiconductor nanostructures have been studied in great details recently as they are good candidates for quantum bits, provided they are coupled to a detector. He…
Divergence at low bias and down-mixing of the current noise in a diffusive superconductor-normal metal-superconductor junction
Elsa Lhotel, Olivier Coupiac, François Lefloch +2
We present current noise measurements in a long diffusive superconductor-normal-metal-superconductor junction in the low voltage regime, in which transport can be partially describ…
Doubled Full Shot Noise in Quantum Coherent Superconductor - Semiconductor Junctions
F. Lefloch, C. Hoffmann, M. Sanquer +1
We performed low temperature shot noise measurements in Superconductor (TiN) - strongly disordered normal metal (heavily doped Si) weakly transparent junctions. We show that the co…
