Abstract
The invention reflects a recognition that prior art templates for colloidal crystal formation do not provide the expected level of three-dimensional periodicity, and further provides a process using an improved template, by which extremely high-quality colloidal crystals are able to be formed. Specifically, the colloidal template of the invention is designed such that the colloidal particles are induced to settle into the desired locations, unlike in prior art templates, thereby settling in an ordered manner.
