Since conventional thermoelectric (TE) materials such as Bi<SUB>2</SUB>Te<SUB>3</SUB> and PbTe contain highly-toxic and rare elements, high-performance TE materials made from non-toxic and Earth-abundant elements need to be developed. Si and metal silicides nanocomposites would be a good candidate of such materials. Generally, metal silicides dispersed into the Si matrix in nanoscale scatter heat carrying phonons effectively, leading to the enhancement in the TE performance of Si. In the present study, the nanocomposites were synthesized by a melt spinning method, in which the size and the distribution of the metal silicides were controlled by changing the cooling rate. The microstructure and the TE properties of nanocomposites composed of Si and various metal silicides (e.g. VSi<SUB>2</SUB>, Mg<SUB>2</SUB>Si, NiSi<SUB>2</SUB>, …) will be presented.
