Control and Detection of Singlet-Triplet Mixing in a Random Nuclear Field
F. H. L. Koppens, J. A. Folk, J. M. Elzerman +7
We observe mixing between two-electron singlet and triplet states in a double quantum dot, caused by interactions with nuclear spins in the host semiconductor. This mixing is suppr…
Density dependence of microwave induced magneto-resistance oscillations in a two-dimensional electron gas
B. Simovic, C. Ellenberger, K. Ensslin +1
We have measured the magneto-resistance of a two-dimensional electron gas (2DEG) under continuous microwave irradiation as a function of electron density and mobility tuned with a…
Domain free high field superlattice transport
T. Feil, H. -P. Tranitz, M. Reinwald +1
The fundamental condition for operating a superlattice (SL) as a Bloch oscillator is a homogeneous electric field alignment under large applied bias. This can be done by combining…
Carbon doped symmetric GaAs/AlGaAs quantum wells with hole mobilities beyond 10^6 cm^2/Vs
C. Gerl, S. Schmult, H. - P. Tranitz +2
Utilizing a novel carbon doping source, we prepared two-dimensional hole gases in a symmetric quantum well structure in the GaAs/AlGaAs heterosystem. Low temperature hole mobilitie…
