We present a method for constructing interface models, based on the se
quential deposition of ions on a substrate surface in conjunction with
energy minimization. The results provide information on how the subst
rate directs the growth of the overlying material and show that as wel
l as factors arising from the misfit between the two materials, both s
urface steps or defects, may lead to the formation of grain boundaries
in the overlying thin film, with implications for supported supercond
ucting thin films and catalysis. [S0163-1829(97)00747-9].
