Abstract
This work presents the emergence of superconductivity in Re-substituted topological Weyl semimetal . Re substitution for Mo sites leads to a sizable enhancement in the superconducting transition temperature (). A record high at ambient pressure in a (room-temperature structure) related sample is observed for the composition (; in comparison, shows a of 0.1 K). The experimental and theoretical studies indicate that Re substitution is doping electrons and facilitates the emergence of superconductivity by enhancing the electron-phonon coupling and density of states at the Fermi level. Our findings, therefore, open a new way to further manipulate and enhance the superconducting state together with the topological states in two-dimensional van der Waals materials.
