Abstract:The O-Ru low index surface systems and the Ru (11 (2) over bar0), (11 (2) over bar1) stepped surface ones were studied by means of the 5-parameter Morse potential theory. The interaction between an adatom and the surface cluster (5-MP), and the correlative data about the adsorption geometry, binding energy, eigenvibration, etc. were obtained, which agree well with the experimental and theoretical results. And what is more, this work predicted the adsorption of 0 atom on Ru (11 (2) over bar1) stepped surface by the theoretical calculation and the inheritance and transformation of the vibration fingerprint property for atomic adsorption state. The factor has also considered that the 0 atom has the tendency to adsorb at 3-fold site on the HCP crystal.
