“…Similar cluster growth phenomenon was reported on Cu on TiO 2 (110) [16]. Small Cu islands of a certain size were created and their density increased linearly up to the saturation coverage where the density increase ceased and the height increase began.…”

We have studied the growth mode and morphology of Ni clusters on a TiO 2 (110) surface with a wide terrace using scanning tunneling microscopy (STM) at a low coverage (less than 3 atoms nm Above the coverage of 1.0 atoms nm -2 , an increase in the cluster height occurs, retaining an almost constant lateral size. It is proposed that the interaction of the Ni cluster and the support surface regulates the Ni cluster size.

In this paper, we propose a kinetic description for the growth and evaporation of oxygen-rich, dirty dust particles, which consist of numerous small islands of different solid materials like Mg 2 SiO 4 , SiO 2 , Al 2 O 3 , Fe and TiO 2 . We assume that the total surface of such a grain collects condensible molecules from the gas phase and that these molecules are rapidly transported by diffusive hopping on the surface to the respective solid islands, where finally the constructive surface chemical reactions take place which increase the size of the grain. Applied to a typical dust forming region in a brown dwarf atmosphere, turbulent temperature fluctuations enable the creation of first seed particles (nucleation) at high supersaturation ratios. These seeds are then quickly covered by different solid materials in a simultaneous way, which results in dirty grains. Our treatment by moment equations allows for the calculation of the time-dependent material composition of the dust grains and the elemental composition of the gas phase. We argue that the depletion of condensible elements from the gas phase by dust formation may be incomplete and occurs in a patchy, non-uniform way which possibly makes metallicity measurements highly uncertain.

“…Long range electrostatic interactions have been observed during the growth of Au on few-layer graphene (FLG) as a result of charge transfer, limiting the island size for a given graphene thickness [27]. Increasing island density with has been observed during growth of Cu on stepped TiO 2 and has been attributed to diffusion barrier modification with increasing due to strain [28]. Earlier experiments on inhomogeneous samples where graphene layers coexist with bare buffer layer 6 ffiffiffi 3 p Â ffiffiffi 3 p have used Co metal atoms as markers to study the conversion form the buffer layer to graphene at higher temperatures [29].…”
