Application and Short Description
The overall project on which we are working involves the design of fullerene and M- dithiolene-based materials, where M=Ni, Pd etc, for photonic applications. The key parameters for such a design are the nonlinear optical (NLO) properties. The increasing demand for faster data processing, storage and distribution can only be fulfilled by ongoing miniaturisation of the basic electronic devices. The traditional silicon-based technologies used nowadays are approaching intrinsic limits in this respect, and new approaches are needed. Photonic technology, where light is used as information carrier instead of electrons, is considered to offer the answer. An important step towards this goal is the development of new photonic materials with large NLO properties by employing nano-derivatives.
The basic concept on which the proposed project is based, involves first, the design of novel dyads employing fullerenes and metal-dithiolenes for photonic applications and second, the solution of several methodological problems, which are of current interest in this area and which are instrumental for the reliable computation of reliable L&NLO properties of the proposed derivatives .
Problems Solved
The successful completion of the study related with the L&NLO properties of Ti@C28 and some other nano-systems.
Scientific and Social Impact
There is currently a great interest in the optical properties of nano-structures due to requirements for materials that allow very high bit-rate in long-distance optical communication. Many devices require materials with NLO figures of merit several orders of magnitude higher than those of materials currently in use. Derivatives with large NLO properties and fast response, such as fullerene-based nano-materials are required for a large number of applications (e.g. fiber optic communication, all optical switching, optical storage media etc). Thus our approach, which includes some state-of-the-art theoretical is expected to lead to some novel and useful photonic nano-materials.
