  • 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 ...
  • Coupling symmetry of quantum dot states 
    Rogge, M.C.; Harke, B.; Fricke, Christian; Hohls, Frank; Reinwald, M.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Physical Society, 2005)
    With noninvasive 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 regime where the current through the dot is too ...
  • Two-path transport measurements on a triple quantum dot 
    Rogge, M.C.; Haug, Rolf J. (College Park, MD : American Physical Society, 2008)
    As an advanced quantum system, a three terminal triple quantum dot with one lead attached to each dot allows us to simultaneously measure a transport along two different paths. Quadruple points with all three dots in ...
