概要
- 論文の詳細を見る
Stranski–Krastanow growth is discussed in the context of a simple classical nucleation model which emphasizes the important role of the wetting layer. The model predicts a rapid transition to a 3D island phase which chiefly depends on the interaction between atoms in the wetting layer and the substrate. A simple analytical expression for the critical thickness at which the transition occurs is derived.
