Аннотация Effect of diffusion on the steady-state nucleation of two-dimensional nanoislands is described analytically. New approach takes self-consistently into account coupling between the kinetics of adatoms near the island edge, their diffusion on the surface and annihilation at other islands. It was shown that due to this coupling the nucleation barrier can considerably differ from that predicted by the thermodynamics and can depend on the diffusion parameters of adatoms. This effect can be used for controlling of the kinetics of nanoisland nucleation.
