Spin blockade in ground state resonance of a quantum dot
A. K. Huettel, H. Qin, A. W. Holleitner +5
We present measurements on spin blockade in a laterally integrated quantum dot. The dot is tuned into the regime of strong Coulomb blockade, confining ~ 50 electrons. At certain el…
Coherent coupling of two quantum dots embedded in an Aharonov-Bohm ring
A. W. Holleitner, C. R. Decker, K. Eberl +1
We define two laterally gated small quantum dots (~ 15 electrons) in an Aharonov-Bohm geometry in which the coupling between the two dots can be broadly changed. For weakly coupled…
Superposition of photon- and phonon- assisted tunneling in coupled quantum dots
H. Qin, A. W. Holleitner, K. Eberl +1
We report on electron transport through an artificial molecule formed by two tunnel coupled quantum dots, which are laterally confined in a two-dimensional electron system of an Al…
Determination of the complex microwave photoconductance of a single quantum dot
H. Qin, F. Simmel, R. H. Blick +3
A small quantum dot containing approximately 20 electrons is realized in a two-dimensional electron system of an AlGaAs/GaAs heterostructure. Conventional transport and microwave s…
Microwave spectroscopy on a double quantum dot with an on-chip Josephson oscillator
A. W. Holleitner, H. Qin, F. Simmel +5
We present measurements on microwave spectroscopy on a double quantum dot with an on-chip microwave source. The quantum dots are realized in the two-dimensional electron gas of an…
