To explore the relaxation process of percolating labyrinthine submonolayer films, we observe in real-time the evolution of a submonolayer film with a coverage of ∼ 0.7 monolayer on SrTiO3(001) at 670 C using scanning tunneling microscopy. We find ...

We study the dependence of the critical size of the nucleus on the density of impurity by carrying out a Monte Carlo simulation. We assume that the impurities are fixed on a crystal surface, and neglect restoration of bonds between an impurity ato...
The stable cluster size and territory for Volmer-Weber growth mechanism are investigated by Monte Carlo simulation. It is shown that the chemical potential dependence for the cluster size shows a different tendency by the surface diffusion treatme...
We carry out the simulation of two component A-B crystals to obtain the critical nucleus size, and show that the nucleus size depends on the surface diffusion of ad atoms on substrate and depends on partial pressure ratio of vapor atoms. We treat ...
