  • High-order cumulants in the counting statistics of asymmetric quantum dots 
    Fricke, Christian; Hohls, Frank; Sethubalasubramanian, Nandhavel; Fricke, Lukas; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2010)
    Measurements of single electron tunneling through a quantum dot (QD) using a quantum point contact as charge detector have been performed for very long time traces with very large event counts. This large statistical basis ...
  • Interaction-induced spin polarization in quantum dots 
    Rogge, M.C.; Räsänen, E.; Haug, Rolf J. (College Park, MD : American Physical Society, 2010)
    The electronic states of lateral many-electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb-blockade peaks are measured. A ...
  • Magneto-photoluminescence spectroscopy of single InAs/AlAs quantum dots 
    Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Meyer, J.M.; Haug, Rolf J.; Pierz, K. (Bristol : IOP Publishing Ltd., 2010)
    We present non-resonant, polarization-resolved magneto-photoluminescence measurements up to 12 T on single InAs/AlAs quantum dots. We observe typical g-factors between 1 and 2, very low diamagnetic shifts due to strong ...
  • Quantum confinement effects in Si/Ge heterostructures with spatially ordered arrays of self-assembled quantum dots 
    Agafonov, Oleksiy B.; Dais, Christian; Grützmacher, Detlev; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2010)
    Magnetotunneling spectroscopy was employed to probe the confinement in vertical Si/Ge double-barrier resonant tunneling diodes with regularly distributed Ge quantum dots. Their current-voltage characteristics reveal a ...
