Experimental investigation of the edge states structure at fractional filling factors
E. V. Deviatov, V. T. Dolgopolov, A. Lorke +2
We experimentally study electron transport between edge states in the fractional quantum Hall effect regime. We find an anomalous increase of the transport across the 2/3 incompres…
Probing a Kondo correlated quantum dot with spin spectroscopy
D. Kupidura, M. C. Rogge, M. Reinwald +2
We investigate Kondo effect and spin blockade observed on a many-electron quantum dot and study the magnetic field dependence. At lower fields a pronounced Kondo effect is found wh…
Coupling symmetry of quantum dot states
M. C. Rogge, B. Harke, C. Fricke +4
With non-invasive methods, we investigate ground and excited states of a lateral quantum dot. Charge detection via a quantum point contact is used to map the dot dynamics in a regi…
Non-invasive detection of charge-rearrangement in a quantum dot in high magnetic fields
C. Fricke, M. C. Rogge, B. Harke +4
We demonstrate electron redistribution caused by magnetic field on a single quantum dot measured by means of a quantum point contact as non-invasive detector. Our device which is f…
Operation of a Bloch oscillator
K. F. Renk, A. Meier, B. I. Stahl +4
We report the operation of a Bloch oscillator. The active medium was a staticvoltage driven, doped GaAs/AlAs superlattice which was electromagnetically coupled to a resonator. The…
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…
