“…Ag growing on Ag(111) shows a very different behaviour [6,12,[17][18][19]. For this system, the growth is three-dimensional at all temperatures below step-flow, indicative of a high step-edge barrier.…”

Molecular beam epitaxy of Cu on Cu( 111 ) was studied using thermal energy He scattering, in the temperature range between 100 and 450 K. Three-dimensional growth was observed in the whole temperature range. To determine the onset of various diffusion processes, submonolayer films formed by deposition at low temperature were annealed. Annealing proceeds in two steps. The first step is interpreted as a change in island shape, the second as Ostwald-ripening. A comparison with homoepitaxy on Pt( 111 ) and Ag( 111 ) is made. Growth manipulation was carried out by artificially increasing the island number density via intervention in the nucleation stage of each layer. The procedures applied were temperature reduction during nucleation as well as pulsed ion bombardment. These techniques enabled the convenient growth of good quality films consisting of a large number of monolayers. Finally, the use of oxygen as a suffactant modifying the growth mode was investigated. Under some growth conditions, pre-exposure of the surface to oxygen was found to induce weak He-intensity oscillations during deposition. The quality of the films grown in tiffs way was, however, low.

“…However, there are still basic unresolved issues for this growth system, so it is chosen here as a case study. Previous transmission electron microscopy 4 and STM studies 5 have revealed wedding-cake-like mounds for growth at 300 K. However, their lateral sizes at 300 K were so large due to rapid terrace diffusion that these morphologies were impacted by substrate dislocations. Other studies of this system were directed toward determination of the ES barrier, still a subject of much controversy.…”

“…An important parameter in the balance between roughening and smoothing is the Ehrlich-Schwoebel (ES) barrier, which hinders downward diffusion across step edges [1,2]. A finite ES barrier results in a roughening of the growing surfaces [3][4][5][6], i.e., to the development of mounds.…”

Steering-Enhanced Roughening during Metal Deposition at Grazing Incidence

1999

View full text Add to dashboard Cite

It is shown that steering may have an important influence on the morphology of growing films. Steering originates from long-range attractive forces between incoming atoms and substrate atoms and leads to preferential arrival of atoms on top of islands. This phenomenon is most pronounced for grazing incidence deposition and results in significantly increased roughness of the growing film. Steering, which is expected to be generally valid but has so far been disregarded in growth studies, is illustrated for the growth of Cu͞Cu(001). [S0031-9007(99)
