ERRATUM TO: ACTIVITY AND DIFFUSIVITY OF OXYGEN IN THE LIQUID DILUTE Bi x Sb 1-x SOLUTIONS

Bismuth and antimony are semimetals which exhibit rhombohedral structure with similar lattice parameters. Binary bismuth-antimony phase diagram indicates complete solubility of these components in both the solid and liquid state. However, below the temperature of about 450 K, the miscibility gap in the solid state may appear. It is demonstrated on the calculated phase diagram [1] shown in Fig.1. It was found that the substitution of Bi atoms by Sb atoms in this lattice modifies the band structure of bismuth. Bi-Sb alloys in the Bi-rich concentration region have a band structure similar to that of pure Bi. It is a semimetal in which the conduction and valence bands overlap at all temperatures. Addition of antimony results in the change of the overlap between bands and the alloy becomes a semiconductor with the energy gap increasing with increasing Sb concentration. What is interesting however, for Sb concentration above 40 % the band gap disappears again, and the semi-metallic character of the alloy returns [2,3]. This unusual behavior brings about a number of interesting transport properties of this alloy resulting from the dependence of the valence and conduction bands on alloy composition, temperature, external pressure and magnetic field. These effects were experimentally demonstrated by Smith and Wolfe [4], who showed that Bi-rich alloys have higher figures of merit (i.e. the ratio of squared Seebeck coefficient divided by the product of the thermal conductivity and electrical resistivity, which determines the usefulness of the material in thermoelectric applications) than those obtained for Bi2Te3 in the temperature range 20–220 K. Later Cuff et al. [5], demonstrated that this effect can be enhanced by the application of transverse magnetic J. Min. Metall. Sect. B-Metall. 54 (2) B (2018) 261 270
