Compact cryogenic Kerr microscope for time-resolved studies of electron spin transport in microstructures
P. J. Rizo, A. Pugžlys, J. Liu +4
A compact cryogenic Kerr microscope for operation in the small volume of high-field magnets is described. It is suited for measurements both in Voigt and Faraday configuration. Cou…
Systematic study of carrier correlations in the electron-hole recombination dynamics of quantum dots
T. Berstermann, T. Auer, H. Kurtze +8
The ground state carrier dynamics in self-assembled (In,Ga)As/GaAs quantum dots has been studied using time-resolved photoluminescence and transmission. By varying the dot design w…
Charge and spin dynamics in a two dimensional electron gas
A Pugzlys, P J Rizo, K Ivanin +5
A number of time resolved optical experiments probing and controlling the spin and charge dynamics of the high mobility two-dimensional electron gas in a GaAs/AlGaAs heterojunction…
Specific Heat of a Fractional Quantum Hall System
F. Schulze-Wischeler, U. Zeitler, C. v. Zobeltitz +5
Using a time-resolved phonon absorption technique, we have measured the specific heat of a two-dimensional electron system in the fractional quantum Hall effect regime. For filling…
Equilibration between edge states in the fractional quantum Hall effect regime at high imbalances
E. V. Deviatov, A. A. Kapustin, V. T. Dolgopolov +3
We experimentally study equilibration between edge states, co-propagating at the edge of the fractional quantum Hall liquid, at high initial imbalances. We find an anomalous increa…
Electrical read-out of the local nuclear polarization in the quantum Hall effect
A. Würtz, T. Müller, A. Lorke +2
It is demonstrated that the now well-established `flip-flop' mechanism of spin exchange between electrons and nuclei in the quantum Hall effect can be reversed. We use a sample geo…
