AbstractA new, versatile approach, applicable to virtually all substrate compositions on laser precision microfabrication of silicon wafers to achieve long-range ordering of colloidal crystals is proposed and demonstrated. In the absence of any surface pattern, the colloid spheres assemble in a randomly packed fashion. However, the presence of a surface pattern induces an ordered packing of the spheres on the lands with hexagonal packing. The colloidal crystal order can be controlled by choosing suitable spatial period of the laser micro-machined template.
