• containing PS beads and the contact angle between the droplet and the substrate, thus influencing the auto-organization process. Comparison of structures without template (simple self-organization) and structures with template (topology assisted self-organization) Although self-organization presents a simple

• structure obtained with different grain orientations, the presence of dislocations limits its applications. So the role of assisted self-organization is to obtain a structure with a single orientation based on a hexagonal lattice of HSQ posts. When we compare the structures obtained by these two techniques
