过冷液体碲在热力学最大值附近的结构变化：一种类似水的情况
Structural changes across thermodynamic maxima in supercooled liquid tellurium: a water-like scenario
摘要：
液体多晶型现象是一个有趣的现象，在一些单组分体系中发现，最著名的是水。通过将液态Te过冷到低于其熔点130 K以上，并同时进行小角和广角X射线散射测量，我们观察到其热力学响应函数在615 K附近有明显的极大值，表明液态多晶型的可能存在。仔细看看底层结构的演变显示了发展的中程秩序冷却后，最强烈的热力学最大值，我们属性键取向有序。我们的研究结果和水之间的惊人的相似之处，尽管缺乏氢键和四面体碲，表明类水的异常可能是一个普遍现象之间的液体系统与竞争的键和密度排序。
英文摘要：
Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K below its melting point and performing simultaneous small-angle and wide-angle X-ray scattering measurements, we observe clear maxima in its thermodynamic response functions around 615 K, suggesting the possible existence of liquid polymorphism. A close look at the underlying structural evolution shows the development of intermediate-range order upon cooling, most strongly around the thermodynamic maxima, which we attribute to bond-orientational ordering. The striking similarities between our results and those of water, despite the lack of hydrogen-bonding and tetrahedrality in tellurium, indicate that water-like anomalies may be a general phenomenon among liquid systems with competing bond- and density-ordering.
