<P>PROBLEM TO BE SOLVED: To provide a thermoelectric material which may give a low thermal conductivity by using an Mg-Si based material that exists in large amounts on the earth without requiring heat treatment, i.e. heating at a temperature equal to or higher than 650°C, and to provide a production method of the thermoelectric material. <P>SOLUTION: There is provided a nano-composite thermoelectric material produced by dispersing nano-particles of a thermoelectric material consisting of Mg<SB POS="POST">2</SB>Si into a base material consisting of amorphous silicon. The proportion indicated by the atomic ratio of each element in the entire material is defined by 0.474≤y/(x+y)≤0.545 in the formula of Mg<SB POS="POST">x</SB>Si<SB POS="POST">y</SB>. There is also provided a production method of the thermoelectric material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
