In-situ scanning tunneling microscopy (STM) has been used to follow the growth mode of gold clusters on TiO2(110) single crystals at room temperature on a cluster-by-cluster basis. Using carefully annealed TiO2(110) surfaces with a relatively low defect density it is possible to isolate cluster growth on step sites from that on terraces. Although the overall growth behavior appears invariant with respect to the morphology of the substrate, our results show that the growth rate is much faster on step edges compared to that on terraces, leading to a bimodal cluster size distribution.
