Revisiting Coulomb diamond signatures in quantum Hall interferometers
N. Moreau, S. Faniel, F. Martins +5
Coulomb diamonds are the archetypal signatures of Coulomb blockade, a well-known charging effect mainly observed in nanometer-sized "electronic islands" tunnel-coupled with charge…
Towards an experimental proof of superhydrophobicity enhanced by quantum fluctuations freezing on a broadband-absorber metamaterial
M. Sarrazin, I. Septembre, A. Hendrickx +9
Previous theoretical works suggested that superhydrophobicity could be enhanced through partial inhibition of the quantum vacuum modes at the surface of a broadband-absorber metama…
2D Rutherford-Like Scattering in Ballistic Nanodevices
S. Toussaint, B. Brun-Barrière, S. Faniel +4
Ballistic injection in a nanodevice is a complex process where electrons can either be transmitted or reflected, thereby introducing deviations from the otherwise quantized conduct…
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…
Scanning Gate Spectroscopy of transport across a Quantum Hall Nano-Island
F. Martins, S. Faniel, B. Rosenow +7
We explore transport across an ultra-small Quantum Hall Island (QHI) formed by closed quan- tum Hall edge states and connected to propagating edge channels through tunnel barriers.…
Structural and electrical characterization of hybrid metal-polypyrrole nanowires
L. Gence, S. Faniel, C. Gustin +5
We present here the synthesis and structural characterization of hybrid Au-polypyrrole-Au and Pt- polypyrrole-Au nanowires together with a study of their electrical properties from…
Imaging Coulomb Islands in a Quantum Hall Interferometer
B. Hackens, F. Martins, S. Faniel +7
In the Quantum Hall regime, near integer filling factors, electrons should only be transmitted through spatially-separated edge states. However, in mesoscopic systems, electronic t…
Dephasing Time of Two-Dimensional Holes in GaAs Open Quantum Dots
S. Faniel, B. Hackens, A. Vlad +6
We report magnetotransport measurements of two-dimensional holes in open quantum dots, patterned either as a single-dot or an array of dots, on a GaAs quantum well. For temperature…
Thermopower of Interacting GaAs Bilayer Hole Systems in the Reentrant Insulating Phase near
S. Faniel, E. Tutuc, E. P. De Poortere +5
We report thermopower measurements of interacting GaAs bilayer hole systems. When the carrier densities in the two layers are equal, these systems exhibit a reentrant insulating ph…
Long dephasing time and high temperature ballistic transport in an InGaAs open quantum dot
B. Hackens, S. Faniel, F. Delfosse +7
We report on measurements of the magnetoconductance of an open circular InGaAs quantum dot between 1.3K and 204K. We observe two types of magnetoconductance fluctuations: universal…
