  • Depinning transitions between adsorbate chains coupled by Friedel oscillations 
    Godzik, G.; Block, T.; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    The low coverage phase transitions of the p(8×1) and the p(5×1) chain structures of the Sr/Mo(112) system have been investigated with low-energy electron diffraction (LEED) at constant coverages. It turns out that both ...
  • Flux-quantum-modulated Kondo conductance in a multielectron quantum dot 
    Fühner, C.; Keyser, U.F.; Haug, Rolf J.; Reuter, D.; Wieck, A.D. (College Park, MD : American Physical Society, 2002)
    We investigate a lateral semiconductor quantum dot with a large number of electrons in the limit of strong coupling to the leads. A Kondo effect is observed and can be tuned in a perpendicular magnetic field. This Kondo ...
  • Murine and human pluripotent stem cell-derived cardiac bodies form contractile myocardial tissue in vitro 
    Kensah, George; Lara, Angelica Roa; Dahlmann, Julia; Zweigerdt, Robert; Schwanke, Kristin; Hegermann, Jan; Skvorc, David; Gawol, Anke; Azizian, Azadeh; Wagner, Stefan; Maier, Lars S.; Krause, Andreas; Dräger, Gerald; Ochs, Matthias; Haverich, Axel; Gruh, Ina; Martin, Ulrich (Oxford : Oxford University Press, 2013)
    AimsWe explored the use of highly purified murine and human pluripotent stem cell (PSC)-derived cardiomyocytes (CMs) to generate functional bioartificial cardiac tissue (BCT) and investigated the role of fibroblasts, ...
  • Photo-excited charge transfer from adamantane to electronic bound states in water 
    Wang, Xiangfei; Krause, Pascal; Kirschbaum, Thorren; Palczynski, Karol; Dzubiella, Joachim; Bande, Annika (Cambridge : RSC Publ., 2024)
    Aqueous nanodiamonds illuminated by UV light produce free solvated electrons, which may drive high-energy reduction reactions in water. However, the influence of water conformations on the excited-state electron-transfer ...
  • Role of domain walls in the abnormal photovoltaic effect in BiFeO 3 
    Bhatnagar, Akash; Roy Chaudhuri, Ayan; Kim, Young Heon; Hesse, Dietrich; Alexe, Marin (London : Nature Publishing Group, 2013)
    Recently, the anomalous photovoltaic (PV) effect in BiFeO 3 (BFO) thin films, which resulted in open circuit voltages (V oc) considerably larger than the band gap of the material, has generated a revival of the entire field ...
  • Shot noise in resonant tunneling through a zero-dimensional state with a complex energy spectrum 
    Nauen, A.; Hohls, Frank; Könemann, J.; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    We investigate the noise properties of a GaAs/AlxGa 1-xAs resonant-tunneling structure at bias voltages where the current characteristic is determined by single electron tunneling. We discuss the suppression of the shot ...
  • Shot noise in self-assembled InAS quantum dots 
    Nauen, A.; Hapke-Wurst, I.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2002)
    We investigate the noise properties of a GaAs-AlAs-GaAs tunneling structure with embedded self-assembled InAs quantum dots in the single-electron tunneling regime. We analyze the dependence of the relative noise amplitude ...
  • Shot noise in tunneling through a single quantum dot 
    Nauen, A.; Hohls, Frank; Maire, Niels; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    We investigate the noise properties of a zero-dimensional InAs quantum dot (QD) embedded in a GaAs-AlAs-GaAs tunneling structure. We observe an approximately linear dependence of the Fano factor and the current as a function ...
