Electrical properties of liquid Au–Si alloys

Abstract The electrical resistivity increases rapidly with the addition of Si to liquid Au, and the composition dependence of the electrical resistivity of liquid Au1−cSic alloys exhibits a maximum at the composition c=0.5. The composition dependence of the thermoelectric power of liquid Au1−cSic alloys shows a rapid change from a positive value on the Au side to a negative value in the composition range c ≧ 0.15 and reaches a minimum of −4 μV/K at the composition c=0.5. The electrical resistivity and the thermoelectric power of liquid Au–Si alloys have been estimated by the Faber–Ziman theory.
