钒酸盐的高压晶体结构及其性质

High pressure crystal structures of orthovanadates and their properties

Daniel Errandonea

摘要:

正钒酸盐的压力诱导相变引起了许多有趣的物理现象。观察到的转变通常涉及材料的大体积塌陷以及电子和振动性质的急剧变化。在某些情况下,相变涉及钒的配位变化,这对钒酸盐的物理性质具有重要影响。在这个角度来看,我们探讨了目前的知识MVO4钒酸盐的压缩下的行为。特别是,我们总结了结构,振动和电子性质的研究和一些说明性的例子,在感兴趣的化合物的高压研究进行了讨论。系统地了解MVO4化合物的高压行为,把重点放在可能与实际应用相关的结果上。本文综述了在极压下正钒酸盐研究的最新进展和未来的挑战,以及可能对相关氧化物研究产生影响的结论。在不久的将来可能导致令人兴奋的突破的主题的一些想法也将被提出。

英文摘要:

Pressure-induced phase transitions in orthovanadates have led to interesting physical phenomena. The observed transitions usually involve large volume collapses and drastic changes in the electronic and vibrational properties of the materials. In some cases, the phase transitions implicate coordination changes in vanadium, which has important consequences in the physical properties of vanadates. In this Perspective, we explore the current knowledge of the behavior of MVO4 vanadates under compression. In particular, we summarize studies of the structural, vibrational, and electronic properties and a few illustrative examples of high-pressure research in the compounds of interest are discussed. A systematic understanding of the high-pressure behavior of MVO4 compounds is presented, putting the emphasis on results that could be relevant for practical applications. Recent advances and future challenges in the study of orthovanadates under extreme pressure will be reviewed, along with conclusions that could have consequences for the studies of related oxides. Some ideas on topics that may lead to exciting breakthroughs in the near future will be presented too.
