Abstract

The intrinsic quantum dot molecules (QDM) structures which exhibit a strong tendancy to size select via property for technological application were demonstrated. These QDM structures obtained a narrowly selected maximum size, independent of film thickness or annealing time. It was found that the growth stagnation was quite surprising given the rapid initial growth of QDM structures and the ample elastic energy available to drive their enlargement. The results show that the QDM structures are potentially of important of importance in fabrication of quantum electronic architectures.
