    The magnetoconductive properties of ultrathin Pb films deposited on Si(111) are measured and compared with density-functional electronic band-structure calculations on two-dimensional, free-standing, 1 to 8 monolayers thick ...
  • Schulze-Wischeler, F.; Mariani, E.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    The activation gap δ of the fractional quantum Hall states was measured as a function of the perpendicular magnetic field. A linear dependence of δ on magnetic field was observed while approaching the spin-polarization ...
  • Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Meisels, R.; Dybko, K.; Kuchar, F. (College Park, MD : American Physical Society, 2002)
    The dynamical scaling of the quantum Hall plateau phase transition in the frequency range 0.1-55 GHz was examined. A universal scaling function was observed, yielding a dynamical exponent 0.9 ± 0.2. The universal behavior ...
  • Hohls, Frank; Zeitler, U.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)
    The frequency dependence of the longitudinal conductivity σxx for frequencies up to 6 GHz was measured. It was possible to access both the real part and the imaginary part of σxx which allowed to perform a new test of ...
  • Hohls, Frank; Zeitler, U.; Haug, Rolf J. (College Park, MD : American Physical Society, 2002)
    The temperature and electric field dependence of the conductivity in the quantum Hall effect (QHE) plateau transition for samples where no universal behavior is found in the conventional temperature dependent peak-width ...
