adsorption and SiO desorption by incident energy of O molecules in the O/Si(001) surface reaction systemTeraoka, Yuden; Yoshigoe, Akitaka; Moritani, Kosuke
Atomic Collision Research in Japan, No.29, p.68 - 70, 2003/00
There are two surface chemical reaction modes in the O/Si(001) system, that is, oxide-layers formation and SiO desorption. We have found that these reaction modes could be selected by changing translational kinetic energy of incident O molecules.
reaction dynamics with Si(001) surfaces as observed by synchrotron radiation photoemission spectroscopyTeraoka, Yuden; Yoshigoe, Akitaka

The translational kinetic energy of incident molecules is an important factor for the induction of surface reactions. We applied supersonic seed molecular beam techniques and high-energy-resolution photoemission spectroscopy using synchrotron radiation to the Si initial oxidation analysis. We have already found out that the saturated oxygen coverage on H
O-chemisorbed Si(001) surfaces depends on the O incident energy. Two potential energy barriers were confirmed in accordance with the first-principles calculation. An action of the incident energy should be confirmed also on clean Si(001) surfaces. Therefore, the incident energy dependence of the O dissociative chemisorption on the clean Si(001) surface has been investigated by photoemission spectroscopy for Si-2p and O-1s core levels to make clear how the incident energy affects the ultra-thin oxide-layers formation.

The oxidation states up to Si
states were formed when the translational kinetic energy of O was 3.0 eV. The time evolustions of each Si oxidation states were in situ measured by using the high resolution photoemission spectroscopy.The translational kinetic energy of 3.0eV randomly enhanced the oxidation on Si(001) surface up to the second layer Si backbonds. It was found that the Si was not observed, thus the dimer Si atoms at the top layer was not surrounded by four oxygen atoms at the initial oxidation stage.
