Two-dimensional photonic crystal fabrication using fullerene films

A two-dimensional rectangular network has been fabricated for the first tim e based on fullerene films using electron lithography. Such a system shows the optical properties of a two-dimensional photonic crystal, which have be en investigated by reflection and transmission methods. An enhancement of t he nonlinear optical properties of the fullerene due to the formation of an open network structure has been found. The pel iodic structure formed from a fullerene film may be transferred easily into the substrate by plasma et ching due to the resistive properties of solid state fullerenes. This metho d allows one to fabricate semiconductor networks and field-induced quantum dot structures.
