Anharmonicity and asymmetry of Landau levels for a two-dimensional electron gas
Stephane Bonifacie, Christophe Chaubet, Benoit Jouault +1
We calculate the density of states of a two dimensional electron gas located at the interface of a GaAlAs/GaAs heterojunction. The disorder potential which is generally created by…

Heating process in the pre-Breakdown regime of the Quantum Hall Efect : a size dependent effect
Y. M. Meziani, C. Chaubet, B. Jouault +4
Our study presents experimental measurements of the contact and longitudinal voltage drops in Hall bars, as a function of the current amplitude. We are interested in the heating ph…

Behavior of the contacts of Quantum Hall Effect devices at high currents : an electronic thermometer
Y. M. Meziani, C. Chaubet, S. Bonifacie +4
This paper reports on an experimental study of the contact resistance of Hall bars in the Quantum Hall Effect regime while increasing the current through the sample. These measurem…
