Abstract/OtherAbstract:
We have presented a theoretical model to elucidate the formation mechanisms of quantum dots (QDs) on patterned substrates, which introduced the perspective that the preferred formation site of QDs is determined by the nonuniformity of wetting layer thickness caused by surface potential. Two different preferred formation sites, low surface curvature or high surface curvature, can be switched through controlling growth temperature or selecting appropriate patterns. The model explains some interesting and puzzling experimental observations, which implies that the established approach could be applicable to the physical understanding of the QDs on patterned substrates.
