WebApr 21, 2024 · In conclusion, with the detailed BKT transition characterization, we observed a 2D superconducting phase in a 3D disordered nonstoichiometric superconducting system. The 3D system was characterized by the short GL coherence length compared to the thickness of the NbTiN film. WebNormal region of Volume Vn Superconducting region of Volume Vs In the absence of applied currents, in Method II, we have found that Moreover, for the simple geometries H is a constant, proportional to the applied field. For a H along a cylinder or for a slab, H is just the applied field. Therefore,

WebSemiconducting two-dimensional (2D) transition metal dichalcogenides (TMDCs) have been heavily studied because of their layer-number-dependent bandgap (1) and outstanding performance as field-effect … WebOccurrence of the Berezinskii-Kosterlitz-Thouless (BKT) transition is investigated by superfluid density measurements for two-dimensional (2D) disordered NbN films with disorder level very close... WebMar 28, 2024 · Unexpectedly, the superconducting transition in the thick FeSe EDLT satisfies the BKT criteria even for the thickness exceeding the bulk coherence length of ∼3 nm. Such a behavior has also been observed in a rather thick 500 nm FeSe film, with an indication of the quasi-2D nature of superconductivity [ 25 ]. projector lcd for church
