  • 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 ...
  • Terahertz detectors based on graphene 
    Gouider, Fathi; Salman, Majdi; Göthlich, Markus; Schmidt, Hennrik; Ahlers, Franz-J.; Haug, Rolf J.; Nachtwei, Georg (Bristol : Institute of Physics Publishing, 2013)
    In this study we present magnetotransport an magnetooptical data obtained in the magnetic field range 0T < B < 7T at detectors patterned in Corbino geometry on epitaxial graphene wafer using a Ge detector. We observed ...
  • Terahertz pulse generation by two-color laser fields with circular polarization 
    Tailliez, C.; Stathopulos, A.; Skupin, S.; Buožius, D.; Babushkin, I.; Vaičaitis, V.; Bergé, L. (Bristol : IOP Publishing Ltd., 2020)
    We study the influence of the polarization states of ionizing femtosecond two-color pulses on the emitted terahertz radiation in gases. A local-current model and plane-wave evaluations justify the previously-reported impact ...
