Ultra-narrow ionization resonances in a quantum dot under broadband excitation
Simon Gustavsson, Mark S. Rudner, Leonid S. Levitov +4
Semiconductor quantum dots driven by the broadband radiation fields of nearby quantum point contacts provide an exciting new setting for probing dynamics in driven quantum systems…
Origins of Nonlocality near the Dirac Point in Graphene
Julien Renard, Matthias Studer, Joshua A. Folk
We present an experimental study of nonlocal electrical signals near the Dirac point in graphene. The in-plane magnetic field dependence of the nonlocal signal confirms the role of…
Optical polarization of localized hole spins in p-doped quantum wells
M. Studer, M. Hirmer, D. Schuh +3
The initialization of spin polarization in localized hole states is investigated using time-resolved Kerr rotation. We find that the sign of the polarization depends on the magneti…
Role of linear and cubic terms for the drift-induced Dresselhaus spin-orbit splitting in a two-dimensional electron gas
M. Studer, M. P. Walser, S. Baer +6
The Dresselhaus spin-orbit interaction (SOI) of a series of two-dimensional electron gases (2DEGs) hosted in GaAs/AlGaAs and InGaAs/GaAs (001) quantum wells (QWs) is measured by mo…
Electron counting in quantum dots
S. Gustavsson, R. Leturcq, M. Studer +5
We use time-resolved charge detection techniques to investigate single-electron tunneling in semiconductor quantum dots. The ability to detect individual charges in real-time makes…
Gate-controlled spin-orbit interaction in a parabolic GaAs/AlGaAs quantum well
M. Studer, G. Salis, K. Ensslin +2
We study the tunability of the spin-orbit interaction in a two-dimensional electron gas with a front and a back gate electrode by monitoring the spin precession frequency of drifti…
