The highest critical temperature of superconductivity Tc has been achieved in cuprates: 133 K at ambient pressure and 164 K at high pressures. As the nature of superconductivity in these materials is still not disclosed, the prospects for a higher Tc are not clear. In contrast the Bardeen-Cooper-Schrieffer (BCS) theory gives a clear guide for achieving high Tc: it should be a favorable combination of high frequency phonons, strong coupling between electrons and phonons, and high density of…

Conventional superconductivity at 203 kelvin at high pressures in the sulfur hydride system
TLDR
S sulfur hydride is investigated, and it is argued that the phase responsible for high-Tc superconductivity in this system is likely to be H3S, formed from H2S by decomposition under pressure, which raises hope for the prospects for achieving room-temperature super conductivity in other hydrogen-based materials.

High-temperature superconductivity in sulfur hydride evidenced by alternating-current magnetic susceptibility
TLDR
The superconductivity identification of sulfur hydride at pressure is reported, employing an in situ alternating-current magnetic susceptibility technique and determines the superconducting phase diagram, finding thatsuperconductivity suddenly appears at 117 GPa and Tc reaches 183 K at 149 GPa before decreasing monotonically with increasing pressure.
High-temperature superconductivity on the verge of a structural instability in lanthanum superhydride
TLDR
It is determined that the high-symmetry high-temperature superconducting Fm-3m phase of LaH10 can be stabilized at substantially lower pressures than previously thought, and a remarkable correlation between superconductivity and a structural instability indicating that lattice vibrations, responsible for the monoclinic structural distortions in LaH 10, strongly affect the superconducted coupling.
