Epitaxial Growth of High Dielectric Contrast Three-Dimensional Photonic Crystals

Abstract

The facile creation of oriented single crystal colloidal assemblies directly on a silicon substrate and conversion to a high refractive index contrast photonic crystal is reported here. The route unveiled has great potential for applications in optoelectronics. The Figure displays the sharp boundary between colloidal crystal growth on patterned substrates and random colloidal assembly formation on unpatterned substrates.
