“…For molten III-V semiconductors, many experimental results, such as viscosity, electrical resistivity etc., were reported so far [4,[8][9][10][11][12][13][14][15][32][33][34]. One goal for these measurements is that the researchers intend to deduce the temperature or composition dependence of the structure changes by analyzing the variations of the macroscopic physical properties.…”

“…As for molten A III -Sb (A III = Al, Ga, In), considerable experimental results of physical properties were reported so far, however, these data were not consistent with each other, especially for electrical resistivity [4,[8][9][10][11][12][13]. Glazov et al analyzed the composition dependence of viscosity and electrical resistivity of molten A III -Sb alloys and concluded that the extreme points (a maximum of the viscosity and a minimum of electrical conductivity) were found in the stoichiometric compounds of A III -Sb alloys.…”

Abstr act Using the d.c. four-probe method, the electrical resistivity of high-purity liquid Sb has been accurately measured as functions of temperature. It is observed that the resistivity of liquid Sb changes abnormally with increasing temperature, which is very different from that of simple liquid metals. Based on the reported structure factor at several temperatures, the results obtained in this work have been discussed and interpreted qualitatively according to Ziman theory. The analysis suggests that the existence of shortrange order structure near the melting point can account for the abnormal phenomenon observed in the resistivity of liquid Sb, in which semimetal-metal transaction takes place in the melting process. At the same time, the progress of the structure change of liquid Sb with temperature has also been pointed out.Keywords: liquid metal, electrical resistivity, structure change.As a kind of primary state of matter, liquid state has its own special structure and physical properties comparing to the solid and gaseous states. In addition, the liquid state is the origin of crystalline and some non-crystalline materials. So it is very important to investigate the liquid, especially the high temperature melts.The study of the electronic transport property of liquid Sb has been paid enough attention, because the electron mean free path in liquid Sb is just a little larger than its mean interatomic distance, which might be a limited case for the application of Ziman theory [1] . Based on the nearly free electron model, this theory has been successfully applied to simple liquid metals. It is concluded that Sb makes semimetal-metal transaction take place in the melting process [2] together with coordination number increasing from 3 of crystal to 4.6 8.7 of liquid in the vicinity of melting temperature [3 5] , but its coordination number is still far below that of a simple liquid metal (~11). The measurement of self-diffusion coefficient indicated that liquid Sb shows semi-metallic behaviour [6] . In addition, the published diffraction patterns near melting temperature show a subsidiary maximum on the high angle side of the main peak [3,7,8] . All these facts suggest that short-range ordered structures exist in liquid Sb at lower temperature. However, by far it is still not clear how the structure changes with temperature due to the difficulties resulting from high temperature and high vapour pressure of liquid Sb.Electrical resistivity is a very useful tool that can help in a general understanding of liquid materials, so the electrical resistivity of liquid Sb was measured by many authors [9 16] , but the results do not agree well with each other. It should be stressed that no valuable results have been obtained because of lower accuracy and dispersive data. In this work, the resistivity of high pure liquid Sb has been accurately measured and the structure change has also been analyzed. ExperimentalThe experimental method used in this note was the d.c. four-probe method. U-shaped quartz cells (fitted w...
