Walk on a Flickering Path: Tracer Diffusion of Adsorbed O Atoms on a Ru(0001) Surface in the Limit of CO Saturation

Previous work has shown that tracer diffusion of adsorbed O atoms on a CO-covered Ru(0001) surface is driven by fluctuations of the CO clusters. Here, a study is presented on the question of whether this diffusion mechanism is suppressed at CO saturation. Experiments were performed using high-speed...
