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…
Observation of inter-edge magnetoplasmon mode in a degenerate two-dimensional electron gas
G. Sukhodub, F. Hohls, R. J. Haug
We study the propagation of edge magnetoplasmons by time-resolved current measurements in a sample which allows for selective detection of edge states in the quantum Hall regime. W…
Shot noise in tunneling through a single quantum dot
A. Nauen, F. Hohls, N. Maire +2
We investigate the noise properties of a zero-dimensional InAs quantum dot (QD) embedded in a GaAs-AlAs-GaAs tunneling structure. We observe an approximately linear dependence of t…
Shot noise in resonant tunneling through a zero-dimensional state with a complex energy spectrum
A. Nauen, F. Hohls, J. Konemann +1
We investigate the noise properties of a GaAs/AlGaAs resonant tunneling structure at bias voltages where the current characteristic is determined by single electron tunneling. We d…
Spin Blockade in Capacitively Coupled Quantum Dots
M. C. Rogge, C. Fuhner, U. F. Keyser +1
We present transport measurements on a lateral double dot produced by combining local anodic oxidation and electron beam lithography. We investigate the tunability of our device an…
