The work is devoted to an analysis of the processes taking place at the surface of the multicomponent crystal during its growth via step-flow mode. It is shown, that at certain conditions nucleation of pure components in a form of nanoislands can take place at the terraces between the steps. The mechanism of formation of such islands is discussed. The criterion for the conditions at which such nucleation takes place is derived.
