摘要：
Oxygen adsorption on Ru(10 (1) over bar 0) is studied using the evolution of the 3d(5/2) photoemission surface core-level shift as a function of coverage. We show that the measurements are sensitive to changes occurring to atoms in both the first and the second layer. This permits a direct demonstration that oxygen adsorbs on this surface in the three-fold hexagonal close-packed site. In addition, the role of the ruthenium second layer in the adsorption process is discussed in terms of the oxygen-metal interaction and heat of adsorption. (C) 2000 Elsevier Science B.V.
