  • 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 ...
  • 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 ...
  • Photoconductivity of graphene devices induced by terahertz radiation at various photon energies 
    Salman, M.; Gouider, F.; Friedemann, M.; Schmidt, H.; Ahlers, Franz-J.; Göthlich, M.; Haug, Rolf J.; Nachtwei, G. (College Park, MD : American Institute of Physics, 2013)
    The influence of a magnetic field on Landau levels (LLs) in graphene-based devices is described via the magneto-optical response induced by terahertz (THz) radiation. For single-layer graphene, the resonance energies of ...
