| Outline of Final Research Achievements |
In this research, we searched novel strategies to improve thermoelectric properties via functions of nanostructuring thermoelectric materials which are abundant on the earth and environmentally friendly. Achievements of this project are as follows: 1) enhancement of carrier concentration from the Gibbs-Thomson effect by dispersion of nanoprecipitates in Si, 2) development of novel low temperature synthesis method for Mg2Si, 3) clarification of the condition for the formation of Si precipitates in plate shape in Mg2Si, and 4) development of an efficient method to study the relation among chemical composition-microstructure-thermoelectric properties.
