“…Recently, it is found that both the compact clusters and the ramified metal aggregates are composed of crystal grains with the size of 10 nm. [16] However, the nickel (Ni) and aluminium (Al) systems on the liquid substrates are two exceptions and their growth mechanism still remains unclear because of several experimental barriers. [17,18] In this Letter, we study the growth mechanism and microstructure of the Ni atomic aggregates on the silicone oil surfaces by atomic force microscopy (AFM).…”

“…oil substrate and washed carefully with acetone and ethanol. [16] After that, the AFM (Veeco DI 3000) measurements were performed immediately for the asprepared samples (it should be mentioned that the Ni samples with d < 8.0 nm could not be imaged suc-cessfully by the optical microscope because of its low resolution, therefore other measurements, e.g. AFM measurement, are necessary for studying the samples).…”

“…3, where one can see that with the increase of the nominal film thickness, the mean diameter Φ m drops quickly, which is quite different from that of the Ag and Au aggregates on the oil surfaces. [16] The formation of the Ni granularities is a process involving nucleation and growth, which depends on the deposition rate, deposition period and the nature of the substrate. During deposition, the concentration of ad-atoms increases with time first.…”

We study the formation mechanism and microstructure of nickel (Ni) atomic aggregates on the silicone oil surfaces by atomic force microscopy (AFM). Initially, the deposited atoms nucleate and form the compact clusters on the liquid surfaces. Then they perform Brownian motion and adhere upon impact. Finally the branched aggregates are formed. The Ni aggregates exhibit granular structure. The mean size of the granularities in the aggregates is of the order of 10 nm and it decreases with the nominal film thickness. The experiment shows that the Ni aggregates perform a directional diffusion towards the sample edge. The interpretation for this phenomenon is presented.

In this article, we report an atomic force microscopy study on the microstructure and the deposition-rate dependence of granular size distribution in copper (Cu) ramified aggregates on a liquid substrate. This study shows that the ramified Cu aggregates are composed of Gaussian size distribution granules, which form immediately after the Cu atoms are deposited. The interesting phenomenon is that the mean diameter F m of the granules exponentially decays and approaches a stable value F c with an increase in the deposition rate f. The granular mean diameter F m slightly changes with the time interval Dt during which the film is kept in the vacuum chamber, owing to the large diffusion coefficient of the Cu granules on the liquid substrates. The experimental behavior strongly depends on the properties of the liquid substrate.

We study the aggregation of silver (Ag) atoms deposited on silicone oil surfaces. It is observed that the apparent Ag coverage of the total area, &, increases linearly with the nominal film thickness h for h < 0:9 nm and its slope k decreases clearly as the deposition flux f increases. Our atomic force microscopy (AFM) observation shows that the average thickness of the atomic aggregates first increases with f , and then approaches a saturation value. Then, the aggregation mechanism of Ag atoms is presented.
