Carbon content drives high temperature superconductivity in a carbonaceous sulfur hydride below 100 GPa

Abstract

We report a previously unobserved superconducting state of the photosynthesized carbonaceous sulfur hydride (C–S–H) system with a maximum TC of 191(1) K below 100 GPa. The properties of C–S–H are dependent on carbon content, and X-ray diffraction and simulations reveal the system remains molecular-like up to 100 GPa.
