Abstract
The screening effect of the process of surface diffusion of adatoms towards the growing nuclei on the kinetics of heterogeneous nucleation is studied. A zone around every growing nucleus is formed, in which the probability of nucleation is practically zero. The saturation nucleus density depends on the correlation between the nucleation and the zone spreading rates. The analysis of the diffusion processes onto the substrate in both cases of sufficiently low and high substrate temperatures permits the derivation of the definitive equality which determines the radius of the diffusion zone. A solution of the problem treating the time dependence of the number of nuclei is suggested for the case of sufficiently high substrate temperatures. The form of the results permits a direct experimental determination of the spreading law of diffusion zones, the surface diffusion coefficient as well as the nucleation rate as a function of the nucleation parameters.
