Document Type and Number:
Japanese Patent JP2017216388
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a superior thermoelectric property in a thermoelectric material including nano particles.SOLUTION: A thermoelectric material comprises: a mixture of a first material having a band gap and a second material different from the first material; and a plurality of nano particles dispersed in the mixture. The first material includes Si and Ge. Supposing that the atomic concentration (unit: atom%) of the second material is "c", and the composition ratio of Si to Ge is "r" in the thermoelectric material, the atomic concentration of the second material and the composition ratio satisfy relational expressions represented by the following expressions (1) and (2): r≤0.62c-0.25 (1); and r≥0.05c-0.06 (2).SELECTED DRAWING: Figure 1
