The growth of multilayer arrays of coherently strained islands self-organizes into a more regular three-dimensional arrangement, providing a possible route to obtain the size uniformity needed for electronic applications of quantum dot arrays.Abstract:
We investigate the growth of multilayer arrays of coherently strained islands, which may serve as ``quantum dots'' in electronic devices. A simple model reproduces the observed vertical correlation between islands in successive layers. However, the arrangement of islands is not simply repeated from layer to layer. Instead, the island size and spacing grow progressively more uniform. In effect, the structure ``self-organizes'' into a more regular three-dimensional arrangement, providing a possible route to obtain the size uniformity needed for electronic applications of quantum dot arrays.read more

TL;DR: In this article, the authors investigated the relationship between optical and structural properties of the MQW structures with a large number of quantum wells and found an obvious split of emission peak and a redshift of the main emission energy in the top layers when the top layer grows above the critical layer thickness.
