Extended Data Fig. 4: Superconducting transition at 272 GPa.
From: RETRACTED ARTICLE: Room-temperature superconductivity in a carbonaceous sulfur hydride
Temperature-dependent quasi-four-point electric resistance measurement of the C–S–H sample at 272 GPa, showing the superconducting transitions at ~280 K. Tc was determined from the onset of superconductivity (see arrow). A superconducting step is observed at the transition midpoint.
