| Outline of Final Research Achievements |
New synthesis techniques have been developed for the formation of Si nanowires with various cross-sectional shapes, such as circle, triangle, squared and hexagonal. CrSi2, MnSi1.7and Mg2Si nanowire bundles were also prepared. The Ca atom extraction from the CaSi2 crystals was done using inositol hexakisphosphate (IP6) in an aqueous solution for the formation of Si nanosheet bundles. The Si-based nanosheet bundles were also synthesized by thermal treatment of CaSi2 powders and CaSi2 microwalls grown on Si substrates under metal chloride vapors. The quantum confinement effect by photoluminescence measurements was observed for the Si nanosheet bundles. Applications to thermoelectric devices have been also investigated. Other II group silicides and acid solutions were also used to form a variety of Si-based nanostructures.
