Contribution

It introduces a model simulating island interactions in quantum dot self-assembly, highlighting the impact of neighboring islands on wetting properties.

Findings

Wetting depends on island density, size distribution, and shape.

Neighbor islands significantly influence wetting behavior.

Implications for optimizing quantum dot self-assembly.

Abstract

The wetting of the homogeneously strained wetting layer by dislocation-free three-dimensional islands belonging to an array has been studied. The array has been simulated as a chain of islands in 1+1 dimensions. It is found that the wetting depends on the density of the array, the size distribution and the shape of the neighbor islands. Implications for the self-assembly of quantum dots grown in the coherent Stranski-Krastanov mode are discussed.
