Abstract
The growth of ultrathin platinum films on a rutile (110) surface has been studied using low-energy ion scattering and x-ray photoelectron spectroscopy. In the temperature range between 160 and 420 K, Pt grows in three-dimensional islands on the surface with the size of the islands increasing with increasing surface temperature and without indication of an interface reaction. Evaporation of Pt in the presence of CO leads to a significantly higher degree of wetting. This behavior is attributed to a chemisorption-induced surfactant effect.
