  • Anisotropy of Zeeman-splitting in quantum dots 
    Könemann, J.; Fal'ko, V.I.; Maude, D.K.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2005)
    By single-electron tunneling spectroscopy we investigate the difference in spin splitting of single-electron resonances in a double-barrier structure subjected to a magnetic field perpendicular (Δ⊥) and parallel (Δ∥) to ...
  • Bimodal counting statistics in single-electron tunneling through a quantum dot 
    Fricke, Christian; Hohls, Frank; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Physical Society, 2007)
    We explore the full counting statistics of single-electron tunneling through a quantum dot using a quantum point contact as noninvasive high bandwidth charge detector. The distribution of counted tunneling events is measured ...
  • Electron transport through and in quantum dot arrays 
    Bayer, Johannes Christian (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2024)
    The present thesis investigates serial quantum dot arrays of different sizes, the double quantum dot, the triple quantum dot, and the quadruple quantum dot. The quantum dot device is based on a two-dimensional electron gas ...
  • Kontrolle zeitaufgelöster Einzelelektronen-Tunnelprozesse in einem Quantenpunkt 
    Wagner, Timo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    In dieser Arbeit werden zwei verschiedene experimentelle Ansätze untersucht, die stochastischen Fluktuationen (Schrotrauschen) zwischen den Einzelelektronen-Tunnelereignissen in einem Quantenpunkt zu kontrollieren. Die ...
  • Quantum dot device tunable from single to triple dot system 
    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. ...
  • Spin droplet formation in quantum dots 
    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 ...
  • Tunneling resonances in quantum dots: Coulomb interaction modifies the width 
    Könemann, Jens; Kubala, Björn; König, Jürgen; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    Single-electron tunneling through a zero-dimensional state in an asymmetric double-barrier resonant-tunneling structure is studied. The broadening of steps in the I-V characteristics is found to strongly depend on the ...
