On the shape formation of the droplet epitaxial quantum dots

In this paper, the shape evolution kinetics of droplet epitaxially grown QDs is investigated. Here, the growth parameter dependent of two distinct QD shape regimes is discussed. We show that the QD shape is determined by the size and the contact angle of the initial droplet. Furthermore, the surface tension dependence on the droplet size is also discussed. Finally, the temporal course of the crystallization process is investigated.
