  • Experimental Determination of the Uncertainty of the Absorption Coefficient of Crystalline Silicon 
    Schinke, Carsten; Peest, Peter Christian; Bothe, Karsten; Schmidt, Jan; Brendel, Rolf; Vogt, Malte R.; Kröger, Ingo; Winter, Stefan; Schirmacher, Alfred; Lim, Siew; Nguyen, Hieu T.; MacDonald, Daniel (Amsterdam : Elsevier, 2015)
    Based on a combined analysis of spectroscopic ellipsometry, reflectance and transmittance measurements as well as spectrally resolved luminescence measurements and spectral responsivity measurements, we present data of the ...
  • Giant anisotropy of zeeman splitting of quantum confined acceptors in Si/Ge 
    Haendel, K.-M.; Winkler, R.; Denker, U.; Schmidt, O.G.; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    Shallow acceptor levels in Si/Ge/Si quantum well heterostructures are characterized by resonant-tunneling spectroscopy in the presence of high magnetic fields. In a perpendicular magnetic field we observe a linear Zeeman ...
  • High-resolution 27Al MAS NMR spectroscopic studies of the response of spinel aluminates to mechanical action 
    Šepelák, Vladimir; Bergmann, Ingo; Indris, Sylvio; Feldhoff, Armin; Hahn, Horst; Becker, Klaus-Dieter; Grey, Clare P.; Heitjans, Paul (Cambridge : Royal Society of Chemistry, 2011)
    The response of the local structure of various types of spinel aluminates, ZnAl2O4 (normal spinel), MgAl2O4 (partly inverse spinel), and Li0.5Al2.5O4 (fully inverse spinel), to mechanical action through high-energy milling ...
  • Nanocrystalline versus microcrystalline Lo2O:B2O 3 composites: Anomalous ionic conductivities and percolation theory 
    Indris, Sylvio; Heitjans, Paul; Roman, H. Eduardo; Bunde, Armin (College Park, ML : American Physical Society, 2000)
    We study ionic transport in nano- and microcrystalline (1−x)Li2O:xB2O3 composites using standard impedance spectroscopy. In the nanocrystalline samples (average grain size of about 20 nm), the ionic conductivity σdc increases ...
  • Spin noise spectroscopy in GaAs 
    Oestreich, Michael; Römer, M.; Haug, Rolf J.; Hägele, D. (College Park, MD : American Physical Society, 2005)
    We observe the noise spectrum of electron spins in bulk GaAs by Faraday-rotation noise spectroscopy. The experimental technique enables the undisturbed measurement of the electron-spin dynamics in semiconductors. We measure ...
