Abstract
X-ray photoelectron spectroscopy (XPS) studies of polycrystalline FeTi surfaces under UHV conditions (2 × 10-10 Torr) revealed the presence of selective interactions between the titanium atoms at the ion-sputtered surface and H2O molecules from the residual gas. Titanium oxide (TiO) becomes during the exposure the dominant surface species as inferred from the Ti(2p 3 2) and O(1s) chemical shifts. The Fe(2p) spectrum characteristic of metallic iron hardly changed during the entire exposure. Sputter-induced structural defects at the FeTi surfaces are supposed to accelerate TiO nucleation.
