摘要：
Two-dimensional (2D) superconductivity in artificial interfaces and atomic-thin layers has gained attention for its exotic quantum phenomena and practical applications. Although bulk van der Waals layered materials have been explored for 2D superconductivity, most of these compounds do not exhibit remarkable properties despite exhibiting 2D characteristics. Here we report a comprehensive analysis of single crystals of Li-intercalated 2H-TaS2 superconductor, suggesting weakly coupled anisotropic superconductivity. Angle-dependent magneto -transport and the Berezinskii-Kosterlitz-Thouless transition confirm quasi-2D superconductivity in 2H-LixTaS2.
