| Outline of Final Research Achievements |
Multi-physics simulation system for light propagation and thermal conduction in an optical disc was developed. Our calculated results clarified the mechanism of super-resolution effect making it possible to read out recording marks smaller than the diffraction limit, and suggested the optimum conditions for the incident light intensity, linear velocity of the disc rotation, and thickness of an active layer. Key materials for the super-resolution effect such as InSb was studied for both crystalline and liquid states by ab-initio calculation. It is found that electronic and optical properties change from semiconductor to metallic behavior due to the melting.
