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.
