  A growth model and parameters obtained in our previous experimental (scanning
tunneling microscopy, KMC) and theoretical (kinetic Monte Carlo simulations,
KMC) studies of Ag/Si(111)-(7x7) heteroepitaxy were used to optimise growth
conditions (temperature and deposition rate) for the most ordered
self-organized growth of Ag island arrays on the (7x7) reconstructed surface.
The conditions were estimated by means of KMC simulations using the preference
in occupation of half unit cells (HUCs) of F-type as a criterion of island
ordering. Morphology of experimentally prepared island structures was studied
by STM. High degree of experimentally obtained island ordering is compared with
the simulated data and results are discussed with respect to the model and
parameters used at the KMC simulations.
