In this paper, we introduce different forms of mobility into a quantitative phase-field model to produce arbitrary Ehrlich-Schwoebel (ES) effects. Convergence studies were carried out in the one-side step-flow model, which showed that the original mobility not only induces the ES effect, but also leads to larger numerical instability with increase of the step width. Thus, another modified form of the ES barrier is proposed, and is found to be more suitable for large-scale simulations. Model… CONTINUE READING
