Abstract

The search for high-temperature superconductivity (HTS) and room-temperature superconductivity (RTS) in hydrogen and hydrogen-rich compounds under high pressure has a long history. Recently, several reports of high superconducting transition temperature (Tc) up to 287 K in hydrides under pressure of up to 267 GPa have appeared. The ultrahigh pressure needed to create the HTS in hydrides has hampered the detailed study of the high-pressure-induced high-Tc superconductivity state, as well as any potential applications. To lower the required pressure, even to zero, we have developed a pressure-quench process (PQP) and have demonstrated it successfully in stabilizing at ambient the high-pressure-induced superconducting phases and other phases in the non-superconducting element Sb, the binary superconducting compound FeSe, and the non-superconducting compound Cu-doped FeSe. It is not inconceivable that the PQP may be adapted for hydrides with Tc approaching room temperature for science and technology. Our recent results and both the opportunities and challenges will be discussed.
