El. Bullock et al., CLEAN AND HYDROXYLATED RUTILE TIO2(110) SURFACES STUDIED BY X-RAY PHOTOELECTRON-SPECTROSCOPY, Surface science, 352, 1996, pp. 504-510
The nature of the chemical bond between the native oxide of Ti metal a
nd various adsorbing species is essential to the understanding of the
biocompatibility of Ti implants. We report here photoemission measurem
ents of the Ti 2p shake-up satellite structure from clean and hydroxyl
ated rutile TiO2(110) surfaces which show that the satellite position
is a sensitive probe of surface bonding. This effect can be explained
in terms of a surface specific relaxation of the photo-induced corehol
e. O 1s core levels are also presented and discussed in the framework
of the atomic structures of these surfaces.
