Times Cited Count：7 Percentile：36.94(Chemistry, Physical)Here we report oxidization properties of Si nanostructures grown on graphite. Si 1s X-ray photoemission spectra using synchrotron radiation are used in order to understand the oxidization pathways. Several Si films, such as 0.4, 2, 5.5 & Aring; were grown on highly oriented pyrolitic graphite (HOPG). In the case of a 0.4 & Aring; Si on HOPG, where different types of Si nanostructures in the form of nanoclusters are present, oxygen reactivity is nearly zero. In contrast, the thick film (5.5 & Aring;), where a bulk-type phase is present, shows a higher degree of reactivity. The results are discussed on the basis of nanostructure geometry, number of constituting Si atoms and cluster size.

Recent research results on translational kinetic energy effects of incident oxygen molecules for Si(001) oxidation are summalized and introduced. The variation of surface temperature dependence of SiO desorption yield, oxygen uptake curves, and chemical bonding states depending on translational kinetic energy of oxygen molecules is described concretely. Eapecially, the translational kinetic energy effects on chemical reaction processes of concurrent oxide-layers formation and SiO desorption are discussed.

The translational kinetic energy of incident molecules is an important parameter for the study of surface chemical reaction mechanisms. New adsorption reactions, induced by the O
translational kinetic energy of several eV, have been found in the O/Si(001) system by applying the surface photoemission spectroscopy with supersonic molecular beam techniques and the high-energy-resolution synchrotron radiation. The termination of dangling bonds affected dominantly the oxidation of dimer backbonds. By controlling the translational kinetic energy of incident O molecules, the formation of oxide-layers with a sub-nanometer scale is possible at room temperature.
