Research Progress of Hydrogen-rich Superconducting Materials under High Pressure

Abstract

 In recent years, hydrogen-rich high-temperature superconducting materials such as H3S and LaH10 discovered by scientists under ultra-high pressure have continuously broken the record of superconducting critical temperature, bringing hope for the ultimate realization of room-temperature superconductivity and thus attracting widespread attention. This article takes the timeline of the discovery of hydrogen-rich superconducting materials as the axis, summarizes the main superconducting material systems and microscopic mechanisms discovered so far, and focuses on introducing the current research progress, problems and challenges faced by high-temperature superconducting materials of hydrogen-rich compounds, providing possible research ideas for the future.
