  • Enhanced localization in Landau-quantized systems induced by very low frequencies 
    Buß, A.; Hohls, Frank; Haug, Rolf J.; Stellmach, C.; Hein, G.; Nachtwei, G. (College Park, MD : American Institute of Physics, 2005)
    Quantum Hall samples with Corbino geometry show an enhanced hysteresis of the I-V curves near the breakdown of the Quantum Hall effect at low AC frequencies. We explain this finding within a hot-electron model by an assumed ...
  • Mobilities and scattering times in decoupled graphene monolayers 
    Schmidt, H.; Lüdtke, T.; Barthold, P.; Haug, Rolf J. (College Park, MD : American Physical Society, 2010)
    Folded single-layer graphene forms a system of two decoupled monolayers being only a few angstroms apart. Using magnetotransport measurements we investigate the electronic properties of the two layers conducting in parallel. ...
  • Nonequilibrium localization in quantum Hall systems at very low frequencies 
    Buss, A.; Hohls, Frank; Schulze-Wischeler, F.; Stellmach, C.; Hein, G.; Haug, Rolf J.; Nachtwei, G. (College Park, MD : American Physical Society, 2005)
    We have measured the conductivity σxx of GaAs GaAlAs Corbino devices under nonequilibrium conditions in the quantum Hall regime at low frequencies from dc up to 10 kHz. At very low frequencies up to 10-20 Hz, σxx shows a ...
