InAs quantum dots (QDs) self-assembled on GaAs(001) at the early stage of growth show scale invariance of the island size distribution, which have been interpreted in the framework of the Mulheran and Blackman theory. The central concept is the capture zone of the growing nucleus properly identified by the Voronoi' cells. We show that the volume distribution of the quantum dots well overlaps the area distribution of the associated Voronoi' cells determined experimentally. Moreover, we evidence…
