Abstract
Method of synthesis of confined colloidal crystals using electrodeposition. The present invention provides a method of growing confined colloidal crystal structures using electrodeposition of monodispersed charged colloid spheres onto a substrate patterned with an array of electroconductive surface relief features on a surface of a substrate. In this approach, control over large-scale ordering is achieved via a planar pattern whose scale is on the order of tens of microns, a regime readily accessed through coarse lithography, laser micromachining, and holography.
