Hydrogen-Rich Superconductors with High Critical Temperature under High Pressure
自从在汞中发现 4.2 K的超导转变温度以来,寻找室温超导体一直是凝聚态物理领域的研究热点.近年来,科学家在高压极端条件下发现了以共价型H3S(Tc=203 K)和离子型LaH10(Tc=250 K)、CaH6(Tc=215 K)为代表的系列高温超导体,先后刷新了超导转变温度纪录,这些工作开启了学界在富氢化合物中寻找室温超导体的新篇章.本文重点介绍了目前高压下二元和三元富氢高温超导体的理论模拟以及实验制备和表征方面的相关研究进展,分析在富氢化合物中发现室温超导体面临的挑战和可能途径,为实现室温超导做出基础性贡献.
Since the discovery of 4.2 K superconductivity in mercury,the search for room-temperature superconductivity has been a hot topic in the field of condensed matter physics.In recent years,scientists have discovered a series of high-temperature superconductivity,represented by covalent H3S(superconducting transition temperature Tc=203 K)and ionic LaH10(Tc=250 K)and CaH6(Tc=215 K)under high pressures.These works have successively broken superconducting temperature records,opening a new era in search for room-temperature superconductivity in hydrogen-rich compounds.This paper focuses on the progress of theoretical prediction,experimental synthesis,and characterization in binary and ternary hydrogen-rich superconductors with high critical temperature under high pressure.Furthermore,it addresses the challenges and potential avenues in the quest for room-temperature superconductors in hydrogen-rich compounds.
