Abstract: | Recent theories for the surface growth are reviewed, which
describe the nucleation kinetics of binary alloys in the first layer
and the nucleation on top of islands in the second layer. In the
first part, describing the submonolayer regime, scaling relations
for the number density of stable islands in dependence of the growth
parameters are derived from an extension of the classical rate
equation approach to binary systems. In the second part a general
stochastic theory is presented that allows one to predict whether
thin films become smooth or rough under non-equilibrium growth
conditions. |
