Rectification in mesoscopic AC-gated semiconductor devices
S. P. Giblin, M. Kataoka, J. D. Fletcher +6
We measure the rectified dc currents resulting when a 3-terminal semiconductor device with gate-dependent conductance is driven with an ac gate voltage. The rectified currents exhi…
High-resolution error detection in the capture process of a single-electron pump
S. P. Giblin, P. See, A. Petrie +6
The dynamic capture of electrons in a semiconductor quantum dot (QD) by raising a potential barrier is a crucial stage in metrological quantized charge pumping. In this work, we us…
Controlled spatial separation of spins and coherent dynamics in spin-orbit-coupled nanostructures
Shun-Tsung Lo, Chin-Hung Chen, Ju-Chun Fan +10
The spatial separation of electron spins followed by the control of their individual spin dynamics has recently emerged as an essential ingredient in many proposals for spin-based…
LO-phonon emission rate of hot electrons from an on-demand single-electron source in a GaAs/AlGaAs heterostructure
N. Johnson, C. Emary, S. Ryu +10
Using a recently-developed time-of-flight measurement technique with 1 ps time resolution and electron-energy spectroscopy, we developed a method to measure the longitudinal-optica…
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…
