层状LiVO2中沿c轴方向随机排列的钒三聚体
Vanadium trimers randomly aligned along the c-axis direction in layered LiVO2
摘要：
在这里，我们讨论了钒三聚体在层状LiVO2和它的硫化物类似物的LiVS2与二维三角晶格的识别。我们使用同步辐射X射线衍射实验的全面结构研究澄清了钒三聚体在LiVO2中沿c轴方向随机排列，而钒三聚体沿c轴方向的长程有序出现在LiVS 2中。我们的研究结果解决了长期存在的问题簇模式的LiVO2和识别三聚体形成的机制提供了实验基础。
英文摘要：
Herein, we discuss the identification of vanadium trimers in layered LiVO2 and its sulfide analog of LiVS2 with two-dimensional triangular lattices. Our comprehensive structural studies using synchrotron X-ray diffraction experiments clarified that vanadium trimers are randomly aligned along the c-axis direction in LiVO2, while the long-range ordering of vanadium trimers along the c-axis direction appears in LiVS2. Our results solve the longstanding issue of cluster patterns in LiVO2 and provide an experimental basis for identifying the mechanism of trimer formation.
