Relaxation of hot electrons in a degenerate two-dimensional electron system: transition to one-dimensional scattering
D. Taubert, C. Tomaras, G. J. Schinner +4
The energy relaxation channels of hot electrons far from thermal equilibrium in a degenerate two-dimensional electron system are investigated in transport experiments in a mesoscop…
An electron jet pump: The Venturi effect of a Fermi liquid
D. Taubert, G. J. Schinner, C. Tomaras +3
A three-terminal device based on a two-dimensional electron system is investigated in the regime of non-equilibrium transport. Excited electrons scatter with the cold Fermi sea and…
Radio frequency pulsed-gate charge spectroscopy on coupled quantum dots
D. Harbusch, S. Manus, H. P. Tranitz +2
Time-resolved electron dynamics in coupled quantum dots is directly observed by a pulsed-gate technique. While individual gate voltages are modulated with periodic pulse trains, av…
Temperature dependence of the visibility in an electronic Mach-Zehnder interferometer
Masayuki Hashisaka, Andreas Helzel, Shuji Nakamura +7
We performed the conductance and the shot noise measurements in an electronic Mach-Zehnder interferometer. The visibility of the interference is investigated as a function of the e…
Phonon-mediated vs. Coulombic Back-Action in Quantum Dot circuits
D. Harbusch, D. Taubert, H. P. Tranitz +2
Quantum point contacts (QPCs) are commonly employed to capacitively detect the charge state of coupled quantum dots (QD). An indirect back-action of a biased QPC onto a double QD l…
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…
