用中子散射法研究了液体CdTe、HgTe和ZnTe的结构。在熔化过程中，发现了截然不同的行为：CdTe和ZnTe在熔体中保持四配位并保持半导体，而HgTe则变成六配位和金属化。这种不同从电负性差异和排斥势硬度的角度进行了讨论。此外，还讨论了Entrobie方面的问题。
The structure of liquid CdTe, HgTe and ZnTe is studied by neutron scattering. Upon melting, drastically different behaviors are found: CdTe and ZnTe keep their fourfold coordination in the melt and remain semiconductors, whereas HgTe becomes sixfold coordinated and metallic. This dissimilarity is discussed in terms of the electronegativity difference and of the repulsive potential hardness. Entropie aspects are also discussed.
