Conduction electrons in acceptor-doped GaAs/GaAlAs heterostructures: a review
Wlodek Zawadzki, Andre Raymond, Maciej Kubisa
We review magneto-optical and magneto-transport effects in GaAs/GaAlAs heterostructures doped in GaAlAs barriers with donors, providing two-dimensional electron gas in GaAs quantum…
Conduction electrons localized by charged magneto-acceptors A in GaAs/GaAlAs quantum wells
M. Kubisa, K. Ryczko, I. Bisotto +3
A variational theory is presented of A and A centers, i.e. of a negative acceptor ion localizing one and two conduction electrons, respectively, in a GaAs/GaAlAs quan…
Reservoir model for two-dimensional electron gases in quantizing magnetic fields: a review
W. Zawadzki, A. Raymond, M. Kubisa
We collect and review works which treat two-dimensional electron gases in quantum wells (mostly GaAs/GaAlAs heterostructures) in the presence of quantizing magnetic fields as open…
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…
