Colloidal Diamond Photonic Bands
ORAL
Abstract
We have designed a new set of patchy tetrahedral colloidal clusters that can self-assemble into a diamond lattice. Like the conventional colloidal diamond of spheres, we find that the diamond lattice of clusters we have assembled exhibits a strong photonic band gap for appropriate parameters. Inverting the lattice leads to a particularly strong band gap after optimizing a few geometric parameters. We also provide a method for achieving the inverse lattice.
