TEMPLATE AND METHODS FOR FORMING PHOTONIC CRYSTALS

摘要

A self-assembled photonic crystal (60, 70, or 80) is formed using a template made by nano-imprint lithography. A layer of imprintable material is deposited (S20) on a substrate, a pattern is imprinted (S30) in the imprintable material to form a template (110) (the pattern of the template being adapted to substantially constrain colloidal particles to a predetermined crystallographic lattice), and colloidal particles (30) are introduced (S40) onto the template, substantially filling the predetermined lattice.
