“…Moreover, the properties of these building blocks can be adjusted by changing their size, which also affects the growth mechanisms, and therefore the film morphology [18,19]. A clear example of the possibility to change the film morphology by varying only the mean cluster size has been given a few years ago by Fuchs et al [18] (Fig. 2) and this study has been completed recently by Brechignac's group for larger cluster sizes [19].…”

However, some authors have argued [18] that the condensation coefficient is not so low. It is interesting to try a different fit of the data -in better agreement with this indication -to give an idea of the uncertainties of the fits.…”

“…It should be noted that the cluster structure can be extensively characterized prior to deposition by several in-flight techniques such as time-of-flight spectrometry, photo-ionization or fragmentation [43]. Moreover, the properties of these building blocks can be adjusted by changing their size, which also affects the growth mechanisms, and therefore the film morphology [18,19].

“…the cluster) and characterize the growth mechanisms. By changing the size of the incident clusters one can change the growth mechanisms [18,19] and the characteristics of the materials. For example, it has been shown that by changing the mean size of the incident carbon clusters, one can modify the properties of the carbon film, from graphitic to diamond-like [20].…”

This paper presents a comprehensive analysis of simple models useful to analyze the growth of nanostructures obtained by cluster deposition. After detailing the potential interest of nanostructures, I extensively study the first stages of growth (the submonolayer regime) by kinetic MonteCarlo simulations. These simulations are performed in a wide variety of experimental situations : complete condensation, growth with reevaporation, nucleation on defects, total or null clustercluster coalescence . . . . The main scope of the paper is to help experimentalists analyzing their data to deduce which of those processes are important and to quantify them. A software including all these simulation programs is available at no cost on request to the author. I carefully discuss experiments of growth from cluster beams and show how the mobility of the clusters on the surface can be measured : surprisingly high values are found. An important issue for future technological applications of cluster deposition is the relation between the size of the incident clusters and the size of the islands obtained on the substrate. An approximate formula which gives the ratio of the two sizes as a function of the melting temperature of the material deposited is given. Finally, I study the atomic mechanisms which can explain the diffusion of the clusters on a substrate and the result of their mutual interaction (simple juxtaposition, partial or total coalescence . . . ).

“…͓DOI: 10.1063/1.1886261͔ Materials built up from nanostructure constituents can have fundamentally different properties than conventional materials. [1][2][3][4][5] Size-dependent effects can be expected to appear when the building blocks are smaller than a certain critical dimension. In addition, interfaces play a major role in thin films derived from nanosized clusters.…”

In this paper we study structural aspects of molybdenum clusters by transmission electron microscopy. The deposited clusters with sizes 4nm or larger show a body-centered crystal (bcc) structure. The clusters are self-assembled from smaller structural units and form cuboids with a typical size of 4nm or larger. With reducing cluster size, the face-centered crystal (fcc) structure appears due to dominance of surface energy minimization, while self-assembly into large cuboids with sizes up to 30nm is still observed. Our observation implies that the basic building blocks of large cuboids are actually not smaller cubes. Annealing leads to cluster coalescence at temperatures ∼800°C, with the crystal habit changing to truncated rhombic dodecahedron for isolated clusters, while the large cuboidally shaped particles become more faceted polyhedra.
