Abstract
Layered metal-rich subsulfides have become a promising area for exploring intriguing properties such as superconductivity, nontrivial topology, and charge density waves; however, despite their extraordinary potential, they have remained largely unexplored. We report a comprehensive analysis of a van der Waals layered metal-rich subsulfide, Nb1.7Ta3.3S2, using a range of measurement techniques, including AC transport, magnetization, and specific heat. Our measurements confirm the occurrence of a type-II superconducting transition at a temperature Tc
= 3.64(2) K. Furthermore, specific heat measurements suggest weakly coupled nodeless superconductivity in Nb1.7Ta3.3S2.
