  • Adsorbate-induced one-dimensional long-range modulation of an epitaxial insulator film 
    Ernst, Wolfgang; Eichmann, M.; Pfnür, Herbert; Jonas, K.-L.; von Oeynhausen, V.; Meiwes-Broer, K.H. (College Park, MD : American Institute of Physics, 2002)
    Using low-energy electron diffraction and scanning tunneling micrsocopy, we found that epitaxial NaCl films grown on Ge(100) with thicknesses up to (at least) 15 monolayers can be modulated with a period of six lattice ...
  • Crossover between monopole and multipole plasmon of Cs monolayers on Si(111) individually resolved in energy and momentum 
    Zielasek, V.; Rönitz, N.; Henzler, M.; Pfnür, Herbert (College Park, MD : American Physical Society, 2006)
    The evolution of the plasmon spectrum of the Si(111) (7×7)-Cs surface has been studied by energy loss spectroscopy individually resolved in energy and momentum during the transition from substrate to Cs overlayer metallization. ...
  • Reactivity and Stability of Ultrathin VOx Films on Pt(111) in Catalytic Methanol Oxidation 
    von Boehn, Bernhard; Scholtz, Lena; Imbihl, Ronald (Dordrecht : Springer Science + Business Media, 2020)
    The growth of ultrathin layers of VOx (< 12 monolayers) on Pt(111) and the activity of these layers in catalytic methanol oxidation at 10−4 mbar have been studied with low-energy electron diffraction, Auger electron ...
  • Suppression of decoherence in a graphene monolayer ring 
    Smirnov, D.; Rode, J.C.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2014)
    The influence of high magnetic fields on coherent transport is investigated. A monolayer graphene quantum ring is fabricated and the Aharonov-Bohm effect is observed. For increased magnitude of the magnetic field, higher ...
  • Switching between one and two dimensions: Conductivity of Pb-induced chain structures on Si(557) 
    Tegenkamp, Christoph; Kallassy, Z.; Pfnür, Herbert; Günter, H.-L.; Zielasek, V.; Henzler, M. (College Park, MD : American Physical Society, 2005)
    We show in a combined study of four-point conductance measurement and tunneling microscopy that surface state conductance induced by one monolayer of Pb on Si(557) can be quasi one dimensional with conductivity values close ...
  • Tunable graphene system with two decoupled monolayers 
    Schmidt, H.; Lüdtke, T.; Barthold, P.; McCann, E.; Fal'Ko, V.I.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2008)
    The use of two truly two-dimensional gapless semiconductors, monolayer and bilayer graphene, as current-carrying components in field-effect transistors (FETs) gives access to special types of nanoelectronic devices. Here, ...
