Abstract

Low-temperature resistivity, Seebeck coefficient, thermal conductivity, and heat-capacity measurements were performed on Ba8Ga16Sn30. This compound crystallizes in a cubic type-VIII clathrate phase, space group I¯43m, with the Baatoms residing inside voids created by a tetrahedrally bonded network of Ga andSn atoms. Ba8Ga16Sn30 exhibits semiconducting behavior above 150 K with a low thermal conductivity and thus may hold potential for thermoelectric applications.
