abstract = {X-ray Photoelectron Spectroscopy (XPS) Was Used to study
the influence of low energy Ar+ ion bombardment, electron
bombardment and Pt deposition on the SrTiO3 (STO) single
crystal electronic structure. Atomic composition changes
were found and attributed to chemical reconstruction of the
STO surface. A clear correlation between the presence of
conducting, low Ti oxidation states in valence band and core
level changes was detected. A strong effect caused by
electron irradiation was ascribed to the electroreduction
process. The influence of lanthanum doping on surface
instability of STO was also discussed. The La doped sample
(STO: $3,75\%$ La) was found to be modified upon Pt metal
deposition to a higher degree than pure STO crystal. (C)
