抄録

We have synthesized single crystalline Ba 8Al xSi x-46 clathrates by using the flux Czochralski (CZ) method with Al-rich melt. The specific electric resistivity, the Seebeck coefficient and the power factor of single crystalline Ba 8Al 14Si 32 were 0.73 mΩcm, 70.0μV/K and 6.8×10 -4V 2/K 2Ωm, respectively. These values are higher than that of single crystalline Ba 8Al 12Si 34clathrate because of the reduced carrier concentration. It is indicated that Al contents and the carrier concentration of single crystalline Ba 8Al xSi 46-x can be controlled by using the flux Czochralski method.
