Using both theoretical analysis and phase field simulation, we reveal robust and facile self-assembly routes, which allow the growth of different stable and ordered nanostructures on various polyhedral nanocrystals (NCs) heteroepitaxially. Our studies show that by increasing the NC's size, transitions from formal growth to ordered quantum dots on the facets and further to ordered quantum dots on the corners take place. The predicted morphologies and their transitions are in excellent agreement with existing widely scattered experimental results. Our study presents a facile and potentially practical route for mass-producing hybrid NCs with well-defined size, shape, composition, and architecture.
