Sensitive radio-frequency measurements of a quantum dot by tuning to perfect impedance matching
N. Ares, F. J. Schupp, A. Mavalankar +9
Electrical readout of spin qubits requires fast and sensitive measurements, but these are hindered by poor impedance matching to the device. We demonstrate perfect impedance matchi…
Magnetic field induced charge redistribution in disordered graphene double quantum dots
K. L. Chiu, M. R. Connolly, A. Cresti +3
We have studied the transport properties of a large graphene double quantum dot under the influence of background disorder potential and magnetic field. At low temperatures, the ev…
Measurement and control of electron wave packets from a single-electron source
J. Waldie, P. See, V. Kashcheyevs +6
We report an experimental technique to measure and manipulate the arrival-time and energy distributions of electrons emitted from a semiconductor electron pump, operated as both a…
Dependence of the 0.7 anomaly on the curvature of the potential barrier in quantum wires
L. W. Smith, H. Al-Taie, A. A. J. Lesage +9
Ninety eight one-dimensional channels defined using split gates fabricated on a GaAs/AlGaAs heterostructure are measured during one cooldown at 1.4 K. The devices are arranged in a…
