“…Among them is the Ge-Te system, which is characterized by one congruently melting compound GeTe (ϑ melt = 725 °C) and two eutectics at 49.85 at.% Te (ϑ eut = 720 °C) and 85 at.% Te (ϑ eut = 375 °C), respectively [4,5]. In addition, a phase with the stoichiometry GeTe 4 was found by crystallization of amorphous alloys around the Ge 20 Te 80 composition [6].…”

The structure of liquid Ge 15 Te 85 , Ge 25 Te 75 and Ge 33 Te 67 alloys has been studied by neutronand X-ray diffraction. Datasets obtained by the two techniques have been modelled simultaneously with the reverse Monte Carlo simulation method. As a result, the first coordination numbers and nearest neighbour distances for the studied alloys were estimated.On the base of the experimental data, Ge-Ge bonding appears to be present in liquid Ge 25

“…Herwig and Wobst [4] revealed that the temperature dependence of the dynamic viscosity of liquid Ge 15 Te 85 shows a remarkable positive deviation from the Arrhenius plot below $525°C. Tsuchiya [5][6][7] established that the density of molten Ge 15 Te 85 shows water-like temperature dependence: it increases by heating up to about 450°C and then decreases with further heating. The specific heat, isothermal compressibility, thermal expansion coefficient determined as functions of temperature exhibit extrema at $407°C [5][6][7].…”

“…Tschirmer et al [2] established that the electrical resistivity decreases by nearly two orders of magnitude within $100°C above the eutectic temperature. Terzieff et al [3] found a minimum of the magnetic susceptibility for liquid Ge 15 Te 85 at about 100°C above T eut . Herwig and Wobst [4] revealed that the temperature dependence of the dynamic viscosity of liquid Ge 15 Te 85 shows a remarkable positive deviation from the Arrhenius plot below $525°C.…”

“…Liquid Ge 15 Te 85 eutectic alloy (T eut = 375°C [1]) exhibits peculiar temperature dependences of various physical properties and it has therefore been very extensively investigated so far. Tschirmer et al [2] established that the electrical resistivity decreases by nearly two orders of magnitude within $100°C above the eutectic temperature.…”
