Oral presentation

Incident kinetic energy of O$$_{2}$$ and surface temperature dependence of initial sticking probability for Si(111)-7$$times$$7 investigated by real-time XPS combined with supersonic molecular beam

So far, we have discussed the adsorption dynamics of O$$_{2}$$ on Si(111)-7$$times$$7 at 300K based on the incident energy dependence of initial sticking probability and saturation coverage. In this conference, the surface temperature dependence of initial sticking probability is reported. At incident energy of 0.06eV at which the precursor-mediated adsorption is dominated, the sticking probability decreases with increasing the surface temperature. This result for adsorption mechanisms is well consistent with that obtained from the incident energy dependence.

Real time observation of O$$_{2}$$ adsorption process on Si(111)-7$$times$$7 at 300K by using synchrotron radiation photoelectron spectroscopy; Time evolution and its correlation of O1s and Si2p

We have reported the incident energy dependece of initial sticking probability, saturation coverage and metastable adsorebed oxygen molecule for O$$_{2}$$ adsorption on Si(111)-7$$times$$7 at 300K. Though the initial adsorption dynamics is emerging, the time evolution of adsorption states progressing to the saturation has not been clear yet. As a reult of measuring the time evolution of both O1s and Si2p XPS, we found the close relationships between those components.
