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...
Relaxation of a well polished, though atomically rough, vicinal surface of SrTiO_3 during annealing was observed by STM. The step patterns are compared with MC simulation of a lattice model.
We study the relation between growth conditions and step spacing of a crystal surface by using the Monte Carlo simulation. In our model, the initial substrate of (001) face includes only one screw dislocations. We measure the step interval under v...
