“…These findings concerning the stabile facets are consistent with results of Thürmer et al 7,8 for the growth of Fe on Fe(100) at 400-450 K. On both surfaces, the (110) and the (001), the system doesn't adopt the steepest facet ({001} and {011} respectively) with an inclination of 45 • to the surface. Instead, facets with smaller angles are favored.…”

The atomistics of metal on metal growth is studied using time resolved STM, SPA-LEED and kinetic Monte-Carlo simulations (KMC). A comparison of the growth behavior seen with STM and KMC is used to show the influence of the fundamental diffusion steps on the morphology of the growing surface in the homoepitaxial system Fe on Fe(110). Especially the influence of a Schwoebel-Ehrlich barrier and an anisotropy in edge diffusion are shown. Details of the transition from a pseudomorphic layer to the relaxed bulk like structure is shown in the examples Fe on W(110). The transition proceeds stepwise and extends over several layers. It involves different metastable arrangements of the layer depending on the deposition temperature.

“…In this case the respective areas of the facets projected onto the starting surface have to be equal. For the (001)-surface this is given by {120}-facets, 7,8 for the (110)-surface by {130}-facets.…”

“…Even though the Zeno-effect has been observed recently on Pt(111) [6], quite typically a coarsening process with appearance of slope selection emerges which has been reported for such diverse systems as Fe(001) [7,8], Cu(001) [9,10], GaAs(001) [11,12], and HgTe(001) [13]. In addition, slope selection seems to be the generic case of solid-on-solid computer simulations [14,12,15].…”

Ehrlich-Schwoebel barrier controlled slope selection in epitaxial growth

2000

We examine the step dynamics in a 1+1 dimensional model of epitaxial growth based on the BCF-theory. The model takes analytically into account the diffusion of adatoms, an incorporation mechanism and an Ehrlich-Schwoebel barrier at step edges. We find that the formation of mounds with a stable slope is closely related to the presence of an incorporation mechanism. We confirm this finding using a Solid-On-Solid model in 2+1 dimensions. In the case of an infinite step edge barrier we are able to calculate the saturation profile analytically. Without incorporation but with inclusion of desorption and detachment we find a critical flux for instable growth but no slope selection. In particular, we show that the temperature dependence of the selected slope is solely determined by the Ehrlich-Schwoebel barrier which opens a new possibility in order to measure this fundamental barrier in experiments.Pacs: 81.10.AjTheory and models of crystal growth; physics of crystal growth, crystal morphology and orientation
