Dependence of the nucleating QDs per hole on the diameter. The number of QDs that nucleate inside a hole is dependent on the hole diameter. The larger the hole, the more QDs nucleate within such a hole, which can be explained by the larger nucleation site and therefore the larger available In reservoir.
