abstract = {A simple analytical model of the mass-transport during the
initial stage of Ge wetting layer formation on Si(l 11) is
developed. The model considers growth of the multilevel Ge
islands observed in recent STM studies as evolution of
pyramids with two bilayer thickness. The pyramid steps flow
together and, as a result, the multilevel island forms if
there exists an upward transport of adatoms from the
substrate surface to the top of the pyramid. The necessary
condition for this is that the step at the pyramid base is
permeable for the adatoms (the adatoms with greater
probability climb up the step than incorporate into it). The
explicit expressions for the step permeability and
incorporation coefficients are obtained. It is shown that
decreasing step permeability is responsible for the
transition from multilevel growth mode to the layer-by-layer
formation of the wetting layer which has been observed under
the increasing deposition rate or/and decreasing growth
temperature. (C) 2004 Elsevier Ltd. All rights reserved.},
