Theoretical calculations have predicted that the latter should be metallized through bandgap closure under pressure, but superconductivity remained elusive in pristine 2H-MoS2 upon substantial compression, where a pressure of up to 60 GPa only evidenced the metallic state. Here we report the emergence of superconductivity in pristine 2H-MoS2 at 90 GPa.
