Abstract

A three dimensional finite element method is used to simulate the kinetic process of island formation in quantum dot superlattices. Depending on the thickness of spacer layers and interruption time, top layer islands can be fully vertically aligned with the same morphology as the buried islands, or can be partially vertically aligned with increasingly less uniform and regular arrangement, or can be alternately misaligned with increasingly uniform and regular arrangement.
