Two-dimensional photonic crystal fabrication using fullerene films

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