| Abstract: | A new method was developed to fabricate colloidal crystals with controllable shapes by taking advantage of the self-assembly of monodisperse spheres at a solid/gas interface. Different shapes such as ring, hemisphere and crater were derived via a control of the substrate wettability and the suspension concentration. PACS 82.70.Dd; 81.16.Dn; 42.70.Qs; 42.25.Fx |
