摘要：

The absence of coarsening in late-stage growth, the evolution of the surface width, and mound shapes in homoepitaxy on Pt(111) around 440 K all agree well with predictions of one-dimensional deterministic growth models for large step-edge barriers. Initial coarsening, which is at variance with these models, is traced to an initially lower effective step-edge barrier that only gradually increases during growth. (C) 1999 Elsevier Science B.V.
