摘　　要：探索高临界温度乃至室温超导体,一直以来都是凝聚态物理研究的梦想之一.尽管理论早就预言,金属氢或富氢化物在高压下可以实现室温超导,然而实验却面临巨大的挑战.最近,研究人员报道在267 GPa的超高压下,C-S-H体系中发现了287.7 K的超导电性,超越了此前LaH10体系中260 K的临界温度记录.该记录更加逼近室温,并为超导材料探索开辟了一条新思路.Exploring high critical temperature even room temperature superconductor is a long-standing pursued dream in condensed matter physics research. Theoretically, room temperature superconductivity may exist in metallic hydrogen or superhydride under extreme high pressure, but the realization requires tremendous challenge in experiments. Recently,scientists claim they find 287.7 K superconductivity in C-S-H system under 267 GPa pressure, which breaks the record of 260 K in La H10 and further approaches room temperature. This study opens a new route to explore superconducting materials near room temperature.
