  • Energy dependence of quasiparticle relaxation in a disordered Fermi liquid 
    Schmidt, T.; König, P.; McCann, E.; Fal'ko, V.I.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)
    Direct measurement of the energy dependence of the inelastic decay rate τ(E) of a quasiparticle state in a disordered conductor was performed using resonant tunneling spectroscopy. Decay rate was obtained from the analysis ...
  • Impact of contacting geometries on measured fill factors 
    Kruse, Christian N.; Wolf, Martin; Schinke, Carsten; Hinken, David; Brendel, Rolf; Bothe, Karsten (London : Elsevier Ltd., 2017)
    The fill factor determined from a measured current-voltage characteristic of a bare solar cell depends on the number and positions of the electrical contacting probes. Nine different geometries for contacting the front ...
  • Magnetic control of electric-field domains in semiconductor superlattices 
    Schmidt, T.; Jansen, A.G.M.; Haug, Rolf J.; Klitzing, K.V.; Eberl, K. (College Park, MD : American Physical Society, 1998)
    Applying magnetic fields up to B = 29 T, we investigate the formation of electric-field domains in Landau-quantized semiconductor superlattices. Surprisingly, the electric-field distribution remains determined by the subband ...
  • 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 ...
  • RKKY interaction in a chirally coupled double quantum dot system 
    Heine, A.W.; Tutuc, D.; Zwicknagl, G.; Schuh, D.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    The competition between the Kondo effect and the Ruderman-Kittel-Kasuya- Yoshida (RKKY) interaction is investigated in a double quantum dots system, coupled via a central open conducting region. A perpendicular magnetic ...
  • Tuning the onset voltage of resonant tunneling through InAs quantum dots by growth parameters 
    Hapke-Wurst, I.; Zeitler, U.; Keyser, U.F.; Haug, Rolf J.; Pierz, Klaus; Ma, Z. (College Park, MD : American Institute of Physics, 2003)
    A study was conducted on the onset voltage of resonant tunneling through indium arsenide (InAs) quantum dots by growth parameters. It was found that the onset voltage of the first step decreased from 200 mV to 0 with ...
