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…
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…
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…
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…
Coherent tunnelling across a quantum point contact in the quantum Hall regime
F. Martins, S. Faniel, B. Rosenow +7
The unique properties of quantum Hall devices arise from the ideal one-dimensional edge states that form in a two-dimensional electron system at high magnetic field. Tunnelling bet…
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…
