  • Godzik, G.; Block, T.; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    The low coverage phase transitions of the (formula presented) and the (formula presented) chain structures of the Sr/Mo(112) system have been investigated with low-energy electron diffraction (LEED) at constant coverages. ...
  • Schwennicke, C.; Schimmelpfennig, J.; Pfnür, Herbert (College Park, MD : American Physical Society, 1993)
    An adsorption study of Xe on both the bare Ge(100) surface, as well as on thin NaCl films grown pseudomorphically on Ge(100), was carried out using high-resolution low-energy electron diffraction. Ordered phases and phase ...
  • Ernst, Wolfgang; Jonas, K.-L.; von Oeynhausen, V.; Tegenkamp, Christoph; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    The Na-induced surface structures on Ge(100) at concentrations below 0.1 monolayer (ML) have been investigated with low-energy electron diffraction and with scanning tunneling microscopy (STM). Annealing and partial ...
  • Tegenkamp, Christoph; Wollschläger, Joachim; Pfnür, Herbert; Meyer zu Heringdorf, Frank-J.; Horn-von Hoegen, Michael (College Park, MD : American Physical Society, 2002)
    Using spot profile analysis in low-energy electron diffraction, we have investigated vicinal Ge(100) surfaces, which were miscut by 2.7° and 5.4°, respectively, in [011] direction with respect to the surface normal. Within ...
  • Godzik, G.; Block, T.; Pfnür, Herbert (College Park, MD : American Physical Society, 2004)
    In this study, carried out by analysis of intensities and spot profiles in low energy electron diffraction, we investigated the influence of electronegative oxygen atoms as dopants on the long range order, the thermal ...
  • Fedorus, A.; Koval, V.; Naumovets, A.; Pfnür, Herbert (College Park, MD : American Institute of Physics, 2001)
    Annealing-driven irreversible structural transitions are studied by low-energy electron diffraction in submonolayer Dy films adsorbed on the Mo(112) surface. In a wide coverage range θ>0.07, Dy overlayers deposited at low ...
