| Abstract
| - Binary colloidal films of polystyrene (PS) spheres and silica spheres were fabricated with a sequential growthmethod using differently sized colloidal particles. In particular, we demonstrate the structures formed by a silicamonolayer growing on top of a PS monolayer and a silica multilayer growing on top of a PS monolayer. By removalof the bottom PS layers, non-close-packed hexagonal, pentagonal, and square silica arrays were obtained at the originalsilica/PS interface. The possible formation mechanism of the non-close-packed structure was discussed, which maybe used to explain how 3D colloidal crystals grow on patterned substrates.
