Acoustic phonon-based interaction between coplanar quantum circuits in magnetic field
M. G. Prokudina, V. S. Khrapai, S. Ludwig +3
We explore the acoustic phonon-based interaction between two neighboring coplanar circuits containing semiconductor quantum point contacts in a perpendicular magnetic field B. In a…
Electron-avalanche amplifier based on the electronic Venturi effect
D. Taubert, G. J. Schinner, H. P. Tranitz +4
Scattering of otherwise ballistic electrons far from equilibrium is investigated in a cold two-dimensional electron system. The interaction between excited electrons and the degene…
Measurement of the Transmission Phase through a Quantum Dot Embedded in One Arm of an Electronic Mach-Zehnder Interferometer
L. V. Litvin, A. Helzel, H. -P. Tranitz +2
We investigate an electronic Mach-Zehnder interferometer with high visibility in the quantum Hall regime. The superposition of the electrostatic potentials from a quantum point con…
Phonon-mediated non-equilibrium interaction between nanoscale devices
G. J. Schinner, H. P. Tranitz, W. Wegscheider +2
Interactions between mesoscopic devices induced by interface acoustic phonons propagating in the plane of a two-dimensional electron system (2DES) are investigated by phonon-spectr…
Signatures of spin in the n=1/3 Fractional Quantum Hall Effect
A. F. Dethlefsen, E. Mariani, H. -P. Tranitz +2
The activation gap Delta of the fractional quantum Hall state at constant filling n =1/3 is measured in wide range of perpendicular magnetic field B. Despite the full spin polariza…
