| Outline of Final Research Achievements |
We performed two types of experiments to prepare thermoelectric material with 3 dimensional cellular structure where conductive electrons are confined in a 2 dimensional space. One route is to sinter the powder sample prepared by high-energy ball milling Si-Al2O3 mixture. Another one is to sinter the powder sample prepared by mixing boehmite nanofiber prepared by oxidization of aluminum nanoparticles and silicon. As results, Si-Al2O3 nanocomposite structure was observed in both samples. In case of solid state precipitation of Si in Mg2Si, precipitates were found to take plate shapes under eigen strain.
