Spin and orbital mechanisms of the magneto-gyrotropic photogalvanic effects in GaAs/AlGaAs quantum well structures
V. Lechner, L. E. Golub, F. Lomakina +12
We report on the study of the linear and circular magneto-gyrotropic photogalvanic effect (MPGE) in GaAs/AlGaAs quantum well structures. Using the fact that in such structures the…
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…
Forming and confining of dipolar excitons by quantizing magnetic fields
K. Kowalik-Seidl, X. P. Vögele, F. Seilmeier +4
We show that a magnetic field perpendicular to an AlGaAs/GaAs coupled quantum well efficiently traps dipolar excitons and leads to the stabilization of the excitonic formation and…
Spatially resolved ultrafast transport current in GaAs photoswitches
L. Prechtel, S. Manus, D. Schuh +2
We apply a pump- and probe-scheme to coplanar stripline circuits to investigate the photocurrent response of GaAs photoswitches in time and space. We find a displacement current pu…
Gating of high-mobility two-dimensional electron gases in GaAs/AlGaAs heterostructures
C. Rossler, T. Feil, P. Mensch +4
We investigate high-mobility two-dimensional electron gases in AlGaAs heterostructures by employing Schottky-gate-dependent measurements of the samples' electron density and mobili…
