The growth of Au clusters on TiO 2 (110)−(1 × 1) and −(1 × 2) single‐crystal surfaces and on ordered Al 2 O 3 films prepared on Re(0001) has been studied by low‐energy electron diffraction (LEED), Auger electron spectroscopy (AES), low‐energy ion scattering spectroscopy (LEISS) and high‐resolution electron energy‐loss spectroscopy (HREELS). The results indicate that Au forms two‐dimensional islands on the TiO 2 (110) surface at initial deposition of Au. On the alumina film, Au initially grows as three‐dimensional clusters. The coverage of Au at which Au clusters change from non‐metallic to metallic properties is found to be >0.3 monolayer equivalent (MLE) of Au deposition based on the energy shift of the surface plasmon measurements.
