Abstract
We explore the use of the pair distribution function to study the self-organization process of Gequantum dots on both nanopatterned and nonpatterned oxidized Si(001) surfaces.Dots formation and ordering upon annealing of a Ge thin film are analyzed. The method we use is not limited to this case study. We show how it can be applied to determine short and long range self-ordering of nanostructures. We support our results by applying a software routine to simulate patterns of dots to finally spot the relevant physical aspects of Ge islands self-assembly.
