Photoluminescence rings in Corbino disk at quantizing magnetic fields
V. Novak, P. Svoboda, M. Cukr +1
Spatially resolved photoluminescence of modulation doped AlGaAs/GaAs heterojunction was investigated in a sample of Corbino disk geometry subject to strong perpendicular magnetic f…
In-plane Magnetic Field Dependent Magnetoresistance of Gated Asymmetric Double Quantum Wells
Yu. Krupko, L. Smrcka, P. Vasek +3
We have investigated experimentally the magnetoresistance of strongly asymmetric double-wells. The structures were prepared by inserting a thin AlGaAs barrier into…
Novel critical field in magneto-resistance oscillation of 2DEG in asymmetric GaAs/AlGaAs double wells measured as a function of the in-plane magnetic field
P. Svoboda, Y. Krupko, L. Smrcka +3
We have investigated the magnetoresistance of strongly asymmetric double-well structures formed by a thin AlGaAs barrier grown far from the interface in the GaAs buffer of standard…
Magnetoresistance and electronic structure of asymmetric GaAs/AlGaAs double quantum wells in the in-plane/tilted magnetic field
O. N. Makarovskii, L. Smrcka, P. Vasek +3
Bilayer two-dimensional electron systems formed by a thin barrier in the GaAs buffer of a standard heterostructure were investigated by magnetotransport measurements. In magnetic f…
Electron conduction within Landau level tails of medium-mobility GaAs / AlGaAs heterostructures
P. Svoboda, G. Nachtwei, C. Breitlow +2
The temperature dependence of both components of the resistivity tensor and has been studied at T 4.2 K within IQHE plateaux around filli…
