Anomalous behaviours of the electrical resistivity of the melt of a typical III-V Ga-Sb system

Abstract: The electrical resistivity, ρ, was measured for the melt of a typical III-V semiconductor system, Ga-Sb, by the direct-current four-probe method. Similarly to the case for solid substitutional alloys, the Nordheim rule almost establishes the concentration dependence of ρ. That is, a rather parabolic form of ρ was obtained as a function of composition; ρ is the deviation of the resistivity from the linear law relating the resistivities of the pure components, liquid Ga and liquid Sb. In spite of this rather sim… Show more

“…The deviation of specific electrical resistivity for liquid Au-Si alloys shows a maximum also at the eutectic composition. Similar maximum of deviation at the eutectic composition has been found also for liquid Ga-Sb [3,4], In-Sb [4], Ag-Ge [8] and Au-Ge [8] alloys, in which a minimum of the temperature coefficient of specific electrical resistivity also exists at the eutectic composition. Therefore, the homogeneous liquids at the eutectic composition for Ag-Si and Au-Si systems show an anomalous behavior derived from the concentration fluctuations.…”

“…The measurements of specific electrical rsistivity and its temperature coefficient were performed with an error within ± 0.5 % and 0.0005 μΩcmK ± -1 respectively judging from the reproducibility of measurements. These error bars are almost same as those in previous similar studies for liquid eutectic alloys [3,4,8].…”
