Molybdenum disulphide has been predicted to undergo an electronic phase transition, but experimental evidence for this is limited. Here, the authors observe a high-pressure semiconducting-to-metallic transition in molybdenum disulphide at 19 GPa, and quantify changes in electronic, vibrational, optical and structural properties.
