Oxygen adsorption on the Ru (10 bar 1 0) surface: Anomalous coverage dependence
S. Schwegmann, A. P. Seitsonen, V. De Renzi +7
Oxygen adsorption onto Ru (10 bar 1 0) results in the formation of two ordered overlayers, i.e. a c(2 times 4)-2O and a (2 times 1)pg-2O phase, which were analyzed by low-energy el…

The Adsorption of Atomic Nitrogen on Ru(0001): Geometry and Energetics
S. Schwegmann, A. P. Seitsonen, H. Dietrich +4
The local adsorption geometries of the (2x2)-N and the (sqrt(3)x sqrt(3))R30^o -N phases on the Ru(0001) surface are determined by analyzing low-energy electron diffraction (LEED)…

Structure and stability of a high-coverage (1x1) oxygen phase on Ru(0001)
C. Stampfl, S. Schwegmann, H. Over +2
The formation of chemisorbed O-phases on Ru(0001) by exposure to O_2 at low pressures is apparently limited to coverages Theta <= 0.5. Using low-energy electron diffraction and den…
