Effect of TiO₂ Film Thickness on the Stability of Au₉ Clusters with a CrO_x Layer.

ABSTRACT: Radio frequency (RF) magnetron sputtering allows the fabrication of TiO₂ films with high purity, reliable control of film thickness, and uniform morphology. In the present study, the change in surface roughness upon heating two different thicknesses of RF sputter-deposited TiO₂ films was investigated. As a measure of the process of the change in surface morphology, chemically -synthesised phosphine-protected Au₉ clusters covered by a photodeposited CrO_x layer were used as a probe. Subsequent to the deposition of the Au₉ clusters and the CrO_x layer, samples were heated to 200 ℃ to remove the triphenylphosphine ligands from the Au₉ cluster. After heating, the thick TiO₂ film was found to be mobile, in con
