“…Therefore each erbium atom is expected to grow to an observable cluster, except it is captured by larger clusters or preferred sites on the substrate. However, Stenzel et al [4] and Velfe et al [33] for Au on NaCl system have shown that the linear dependence of R-J is not necessarily related to the nucleation at preferred sites. In Walton's theory the nucleation rate is determined by the formation of stable cluster.…”

“…In Walton's theory the nucleation rate is determined by the formation of stable cluster. However, Velfe et al [33] predicted that only those clusters which obtain the immobile size without colliding with larger clusters can contribute to a visible nucleation. That means that nearly all mobile clusters are captured by immobile ones.…”

Nucleation kinetics of UHV deposited erbium on amorphous carbon at room temperature and for atom arrival rates of 1.5 × 10 13 -1.8 × 10 14 atoms/cm 2 s is studied. For all deposition rates, the density of nuclei increased with time to a saturation value and remained stationary. It was found that the nucleation rate is linearly dependent on the deposition rate, indicating that a single-adatom constitutes a stable nucleus. At lower deposition rates (up to R = 1 × 10 14 atom/cm 2 s), the saturation density is constant and independent of R but at higher rates it increases with R according to the mathematical function n s = a + b exp(R/c). It is shown that the nucleation theory usually used to explain the experimental work needs some revision. For measured condensation coefficients, the diffusion length of adatoms x s = (1.53 ± 0.01) nm, and the difference between adsorption and surface diffusion energies, E a − E sd = (0.12 ± 0.01) eV are estimated.

“…All three assumptions have been refuted long ago in the VW growth mode. [35][36][37] The results of these earlier studies have been attributed to diffusion of clusters as large as 40 atoms via interfacial glide, 38 which needs little activation energy when the misfit is large. 39 Pd and Ni clusters of more than 30 atoms have been reported to float like rafts on the W͑110͒ surface.…”

The influence of interfactants ͑Au, Ag͒ on the growth of Pb on Si͑111͒ is studied by low-energy electron microscopy in the temperature range from 260 K to 460 K. On the Si͑111͒-(7ϫ7) surface Pb grows in the Stranski-Krastanov mode, on the Si͑111͒-(ͱ3ϫͱ3)R30°-Au and on the Si͑111͒-(6ϫ6)-Au surface in the quasi-Frank-van der Merwe ͑layer-by-layer͒ mode. On the Si͑111͒-(ͱ3ϫͱ3)R30°-Ag surface the growth mode changes from layer-by-layer below 300 K to the Stranski-Krastanov mode above 300 K. The temperature dependence of the growth cannot be explained by thermodynamics but is governed by kinetics. The analysis of the maximum island density in terms of the atomistic nucleation theory gives acceptable values for nucleus size and energies only in the layer-by-layer growth regime. In the Stranski-Krastanov growth regime abnormal values are obtained that are attributed to high cluster mobility on the initial two-dimensional layer. The conditions leading to quasi-Frank-van der Merwe growth are discussed.
