Nucleation on a stepped surface with an Ehrlich-Schwöbel barrier
Original language description
During deposition on a stepped surface the growth mode depends on the conditions such as temperature T, deposition rate F and width of the terraces w. In this work we studied the influence of all the above mentioned characteristics using the kinetic Monte Carlo (kMC) technique. We concentrated on the conditions on the terrace at the moment of the first nucleation. The critical density of monomers for nucleation eta(m) decreases with the width of the terrace and the nucleation starts at surprisingly lowdensities of monomers. We tested several definitions of the critical width for nucleation w(c) used in various articles in the past and we compared our results with results of the analytical steady-state mean-field model (Ranguelov and Altman 2007 Phys.Rev. B 75 245419). To check how the simplified assumption about the steady-state regime during deposition influences the resulting dependence of w(c) similar or equal to (D/F)(kappa), we set and also solved a time-dependent analytical mod
