Oxygen adsorption and ordering on Ru(101¯0)
Abstract
The dissociative oxygen chemisorption on the Ru(101¯0) surface has been studied by monitoring the changes of the O 1s and Ru 3d5/2 core levels and by measuring the evolution of the diffraction pattern during oxygen exposure at 270 K. The sensitivity of core level binding energies to different geometrical configurations, together with the measurements of the oxygen-induced diffraction spot profile along the [0001] and [12¯10] directions, permit us to follow the details of formation of the c(2×4) and the (2×1)p2mg ordered structures.
