Outline of Final Research Achievements

In order to fabricate a thermoelectric conversion material composed of crystalline silicon, the strained silicon structure with the width of 100 nm were successfully photoinduced by the irradiation of IR femtosecond laser double pulses. The self-assembled nanostructures of strained silicon inside Si crystal could be formed via interactions between the electron plasma excited by the first arrival pulse with the electric field of the secondary arrival pulse. Such periodic nanostructures composed of the strained silicon indicate higher electrical and lower thermal conductivities.
