Self-ordered Ti- and Co-silicide nanoislands on vicinal Si(111) template as a function of the initial metal coverage: while a degree of this kind of SO for Co-silicide islands was higher than for the Ti-silicide ones, for both types of islands an inverse dependence of order parameter on coverage was found [more details, see ref. 20 in Publication List].
