Abstract

Upon thermal annealing at or above room temperature (RT) and at high hydrostatic pressure P similar to 155 GPa, sulfur trihydride H3S exhibits a measured maximum superconducting transition temperature T-c similar to 200K. Various theoretical frameworks incorporating strong electron-phonon coupling and Coulomb repulsion have reproduced this record-level T-c. Of particular relevance is that experimentally observed H-D isotopic correlations among T-c, P, and annealed order indicate an H-D isotope effect exponent a limited to values
