  • Interplay of Electron and Nuclear Spin Noise in n -Type GaAs 
    Berski, Fabian; Hübner, Jens; Oestreich, Michael; Ludwig, Arne; Wieck, A.D.; Glazov, Mikhail (College Park, MD : American Physical Society, 2015)
    We present spin-noise spectroscopy measurements on an ensemble of donor-bound electrons in ultrapure GaAs:Si covering temporal dynamics over 6 orders of magnitude from milliseconds to nanoseconds. The spin-noise spectra ...
  • Optical spin noise of a single hole spin localized in an (InGa)as quantum dot 
    Dahbashi, Ramin; Hübner, Jens; Berski, Fabian; Pierz, Klaus; Oestreich, Michael (College Park, MD : American Physical Society, 2014)
    We advance spin noise spectroscopy to the ultimate limit of single spin detection. This technique enables the measurement of the spin dynamic of a single heavy hole localized in a flat (InGa)As quantum dot. Magnetic field ...
  • 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 ...
