Investigation on the crystal structure of NbRe and nitrided NbRe thin film

Non-centrosymmetric superconductors are a fascinating class of materials, where exotic properties (multi-gap and nodal superconductivity, huge upper critical field, helical vortex-state, non-trivial topological effects) are observed. Our aim is to collect elastic scattering data on both pure and nitride NbxRe1-x thin films suitable for both X-ray diffraction and pair distribution function analyses. In particular, we want to probe in detail the NbxRe1-x crystal structure of as grown and post-annealed films, as well as the structural rearrangements occurring after its nitridation. These data will be crucial to gain insights in the relationship between the structural and the exotic physical properties characterizing these materials.

非中心对称超导体（Non-centrosymmetric superconductors）是一类极具研究价值的材料，其展现出多能隙与节点超导性、极高的上临界场、螺旋涡旋态以及非平庸拓扑效应等诸多奇特物性。本数据集旨在收集纯相及氮化态NbxRe1-x薄膜的弹性散射数据，该类样品可同时用于X射线衍射（X-ray diffraction）与对分布函数（pair distribution function）分析。具体而言，我们将详细表征原始生长态与后退火处理的NbxRe1-x薄膜的晶体结构，同时探究其氮化过程中发生的结构重排行为。该数据集将为揭示这类材料的结构特征与奇特物性之间的内在关联提供关键支撑。
