Structure, thermal, and transport properties of the clathrates Sr8Zn8Ge38, Sr8Ga16Ge30, and Ba8Ga16Si30
(2004-07)
The structural parameters, thermal properties, and transport properties of three type I
clathrates, namely Sr8Zn8Ge38, Sr8Ga16Ge30, and Ba8Ga16Si30, have been determined at or below room
temperature. The structural ...
Transport properties of Na8Si46
(2001-10)
We report on transport properties of polycrystalline Na8Si46 in the temperature range 10 to 300
K. The compound is a type I clathrate with Na incorporated into polyhedra formed by framework Si
atoms. Seebeck coefficient ...
