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…
Counterflow of electrons in two isolated quantum point contacts
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We study the interaction between two adjacent but electrically isolated quantum point contacts (QPCs). At high enough source-drain bias on one QPC, the drive QPC, we detect a finit…
Domain free high field superlattice transport
T. Feil, H. -P. Tranitz, M. Reinwald +1
The fundamental condition for operating a superlattice (SL) as a Bloch oscillator is a homogeneous electric field alignment under large applied bias. This can be done by combining…
