    Absorption or resonance Raman scattering are often used to identify and even quantify carotenoids in situ. We studied the absorption spectra, the Raman spectra and their resonance behavior of β-carotene in different molecular ...
  • 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 ...
  • Steckenreiter, Verena; Walter, Dominic C.; Schmidt, Jan (Melville, NY : American Institute of Physics Inc., 2017)
    Based on contactless carrier lifetime measurements performed on p-type boron-doped Czochralski-grown silicon (Cz-Si) wafers, we examine the rate constant Rde of the permanent deactivation process of the boron-oxygen-related ...
  • Keyser, U.F.; Fühner, C.; Borck, S.; Haug, Rolf J.; Bichler, M.; Abstreiter, G.; Wegscheider, W. (College Park, MD : American Physical Society, 2003)
    A small tuneable quantum ring with less than ten electrons was shown to exhibit Aharonov-Bohm oscillations as well as Coulomb blockade. At strong coupling to the leads, evidence of a Kondo effect induced by a single spin ...
  • Schmidt, T.; Haug, Rolf J.; Fal'ko, V.I.; v. Klitzing, K.; Förster, A.; Lüth, H. (College Park, MD : American Physical Society, 1997)
    The local density of states of heavily doped GaAs is explored at high magnetic fields, where only a single or few Landau bands are occupied. Our experiment is based on resonant tunneling through impurity states and images ...
  • Langer, Thomas; Förster, D.F.; Busse, C.; Michely, T.; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2011)
    The sheet plasmon of graphene on Ir(111) was investigated in this paper by means of high-resolution electron energy loss spectroscopy. The perfect lateral coordination of sp2-hybridized C atoms on a large scale is manifested ...
  • Murphy, J.D.; Al-Amin, M.; Bothe, K.; Olmo, M.; Voronkov, V.V.; Falster, R.J. (College Park, MD : American Institute of Physics, 2015)
    Supersaturated levels of interstitial oxygen in Czochralski silicon can lead to the formation of oxide precipitates. Although beneficial from an internal gettering perspective, oxygen-related extended defects give rise to ...
