Fabrication of three-dimensional hierarchical nanostructures using template-directed colloidal assembly

Abstract

Optical effects in template-directed colloidal assembly are explored to fabricate microscale patterns with integrated three-dimensional (3D) nanostructures. This method allows the patterning of periodic nanostructures in arbitrarily designed regions by controlling particle assembly and light illumination. Using both “bottom-up” and “top-down” methods, this approach enables low-cost fabrication of hierarchical devices.
