アルミ系正20面体準結晶の熱電材料としての可能性 Possibility of Al-based Icosahedral Quasicrystal as a Thermoelectric Material
The thermoelectric properties of icosahedral AlPdRe quasicrystals obtained by replacing Re with transition metals have been studied in according with the guiding principle of Weakly Bonded Rigid Heavy Clusters (WBRHCs) . The dimensionless figure of merit (<I>ZT</I>) was increased 2.6 times from 0.08 to 0.21 by Fe substitution for Re in the icosahedral AIPdRe quasicrystals. It is then possible to improve the thermoelectric performance of <I>i</I>-AlPdRe by searching over a wider range of composition, including the addition of a fourth element or fourth and fifth elements.
