Pattern Formation in Multilayer Growth
While the growth of islands discussed in the last chapter could be considered as an essentially two-dimensional problem, the morphology of a multilayer film is determined not only by the transport of atoms within an atomic layer (intralayer transport), but in addition by the transport of atoms between different atomic layers (interlayer transport). In the same way as the evolution of island shapes with temperature can be understood in terms of the activation of atomic processes along the step edge, the sequence of multilayer growth regimes that unfold as a function of temperature is governed by the activation of atomic processes which enable the exchange of atoms between different atomic layers.
