    Electronic transport through a two-path triple-quantum-dot system with two source leads and one drain is studied and the interaction between the two paths is analyzed. We observe a channel blockade as a result of interchannel ...
  • Bayer, Johannes C.; Wagner, Timo; Rugeramigabo, Eddy P.; Haug, Rolf J. (College Park, MD : American Physical Society, 2017)
    Semiconductor quantum dots are potential building blocks for scalable qubit architectures. Efficient control over the exchange interaction and the possibility of coherently manipulating electron states are essential ...
  • Rogge, M.C.; Fühner, C.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2007)
    We study the magnetoconductance of lateral quantum dots in high magnetic fields. We use spin blockade and Kondo effect to investigate the spin configuration and the spin filling mechanism and find a dependence on the ...
  • Rogge, M.C.; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    We present a lateral quantum dot device which has a tunable number of quantum dots. Depending on easily tunable gate voltages, one, two or three quantum dots are found. They are investigated in transport and charge detection. ...
  • Mühle, A.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2008)
    We demonstrate the tunability of a GaAsAlGaAs quantum ring showing coherent Aharonov-Bohm oscillations up to a gate voltage regime where the ring splits into three quantum dots. This is explained based on the structure's ...
  • Rogge, M.C.; Räsänen, E.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2011)
    A lateral quantum dot with approx. 50 electrons is analyzed in high perpendicular magnetic fields. In a regime with two Landau levels (LL) in the quantum dot information about the spin structure is gained by investigating ...
  • Kotzian, M.; Rogge, M.C.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    We present transport measurements on a lateral triple quantum dot with a star-like geometry and one lead attached to each dot. [1] The system is studied in a regime close to established quadruple points, where all three ...
