Vertical Correlations and Anti-Correlations in Multi-Layered Arrays of 2D Quantum Islands
Abstract
A remarkable feature of multi-sheet arrays of 3D islands is that the buried islands in successive sheets are spatially correlated. At the surface, new islands were observed to be formed directly above buried islands. The existing theory explaining well the correlation accounts the strain created by buried islands and shows that energetically preferred sites for nucleation of islands of the second sheet occur above buried islands, buried islands were approximated as elastic point defects, and the crystal was treated as elastically isotropic medium.
