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…
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…
Response of the two-dimensional electron gas of AlGaAs/GaAs heterostructures to parallel magnetic field
V. S. Khrapai, E. V. Deviatov, A. A. Shashkin +1
We study the transport properties of the two-dimensional electron gas in AlGaAs/GaAs heterostructures in parallel to the interface magnetic fields at low temperatures. The magnetor…
