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…
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…
Formation of quantum dots in the potential fluctuations of InGaAs heterostructures probed by scanning gate microscopy
P. Liu, F. Martins, B. Hackens +6
The disordered potential landscape in an InGaAs/InAlAs two-dimensional electron gas patterned into narrow wires is investigated by means of scanning gate microscopy. It is found th…
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.…
Transport inefficiency in branched-out mesoscopic networks: An analog of the Braess paradox
M. G. Pala, S. Baltazar, P. Liu +7
We present evidence for a counter-intuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks. A numerical si…
On the imaging of electron transport in semiconductor quantum structures by scanning-gate microscopy: successes and limitations
Hermann Sellier, Benoit Hackens, Marco Pala +6
This paper presents a brief review of scanning-gate microscopy applied to the imaging of electron transport in buried semiconductor quantum structures. After an introduction to the…
