Optical orientation of electron spins in GaAs quantum wells
S. Pfalz, R. Winkler, T. Nowitzki +4
We present a detailed experimental and theoretical analysis of the optical orientation of electron spins in GaAs/AlAs quantum wells. Using time and polarization resolved photolumin…
Thermopower of a Kondo-correlated quantum dot
R. Scheibner, H. Buhmann, D. Reuter +2
The thermopower of a Kondo-correlated gate-defined quantum dot is studied using a current heating technique. In the presence of spin correlations the thermopower shows a clear devi…
Magneto-capacitance probing of the many-particle states in InAs dots
Oliver S. Wibbelhoff, Axel Lorke, Dirk Reuter +1
We use frequency-dependent capacitance-voltage spectroscopy to measure the tunneling probability into self-assembled InAs quantum dots. Using an in-plane magnetic field of variable…
Phonon Excitations of Composite Fermion Landau Levels
F. Schulze-Wischeler, F. Hohls, U. Zeitler +3
Phonon excitations of fractional quantum Hall states at filling factors nu = 1/3, 2/5, 4/7, 3/5, 4/3, and 5/3 are experimentally shown to be based on Landau level transitions of Co…
