Enhancing Spin Diffusion in GaAs Quantum Wells: The Role of Electron Density and Channel Width
B. W. Grobecker, A. V. Poshakinskiy, S. Anghel +3
This study explores the relationship between spin diffusion, spin lifetime, electron density and lateral spatial confinement in two-dimensional electron gases hosted in GaAs quantu…
Persistent Spin Helix Manipulation by Optical Doping of a CdTe Quantum Well
F. Passmann, S. Anghel, T. Tischler +6
Time-resolved Kerr-rotation microscopy explores the influence of optical doping on the persistent spin helix in a [001]-grown CdTe quantum well at cryogenic temperatures. Electron…
Gate-Control of Anisotropic Spin Transport and Spin Helix Dynamics in a Modulation-Doped GaAs Quantum Well
S. Anghel, F. Passmann, A. Singh +10
Electron spin transport and dynamics are investigated in a single, high-mobility, modulation-doped, GaAs quantum well using ultrafast two-color Kerr-rotation micro-spectroscopy, su…
High fidelity optical preparation and coherent Larmor precession of a single hole in an InGaAs quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy with photocurrent readout to directly probe the dynamics of a single hole spin in a single, electrically tunable self-assembled quantum…
Electrical control of inter-dot electron tunneling in a quantum dot molecule
K. Müller, A. Bechtold, C. Ruppert +8
We employ ultrafast pump-probe spectroscopy to directly monitor electron tunneling between discrete orbital states in a pair of spatially separated quantum dots. Immediately after…
Excited State Quantum Couplings and Optical Switching of an Artificial Molecule
K. Müller, G. Reithmaier, E. C. Clark +6
We optically probe the spectrum of ground and excited state transitions of an individual, electrically tunable self-assembled quantum dot molecule. Photocurrent absorption measurem…
