Abstract

We study the self-assembly of ordered nanostructures, that is, nanorings (NRs) and quantum dots (QDs), epitaxially grown on a polygonal cross-section nanowire (PCS-NW) using both theoretical and phase-field modeling. Our studies show that, by increasing the PCS-NW size, transitions from ordered NRs to ordered QDs on facets and further to ordered QDs on ridges occur. The predicted morphologies and their transitions are in excellent agreement with existing experiments. Our study suggests a novel approach to fabricate ordered nanostructures on nanowires.
