In situ reduction of charge noise in GaAs/AlGaAs Schottky-gated devices
Christo Buizert, Frank H. L. Koppens, Michel Pioro-Ladriere +5
We show that an insulated electrostatic gate can be used to strongly suppress ubiquitous background charge noise in Schottky-gated GaAs/AlGaAs devices. Via a 2-D self-consistent si…
Nonequilibrium phenomena in adjacent electrically isolated nanostructures
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We report on nonequilibrium interaction phenomena between adjacent but electrostatically separated nanostructures in GaAs. A current flowing in one externally biased nanostructure…
Nonequilibrium interactions between two quantum circuits
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We briefly overview our recent results on nonequilibrium interactions between neighboring electrically isolated nanostructures. One of the nanostructures is represented by an exter…
Edge Channel Interference Controlled by Landau Level Filling
L. V. Litvin, A. Helzel, H. -P. Tranitz +2
We study the visibility of Aharonov-Bohm interference in an electronic Mach-Zehnder interferometer (MZI) in the integer quantum Hall regime. The visibility is controlled by the fil…
