论文摘要
室温超导性是人类一直在追逐一个世纪的梦想。近年来，H3S，LAH10和C-S-H系统的合成逐渐使这个梦想成为现实。但是，基于氢的超导体金属化所需的极端压力限制了它们的应用。在这项工作中，我们设计了一系列的高温超导体，通过将重的稀土元素yb/lu掺入苏达岩状的杂质氢化物中，可以在中等压力下保持稳定。特别是，Y3LUH24，YLUH12和YLU3H24的临界温度分别为283 K，275 K和288 K，它们接近或已达到室温，这些液体的稳定压力约为120 GPA，大约低于室温大约低于室温的室温。我们的工作提供了一种有效的方法，用于使用高-TC的低压稳定基于氢的超导体的设计，并将刺激进一步的实验探索。
Room temperature superconductivity is a dream that mankind has been chasing for a century. In recent years, the synthesis of H3S, LaH10 and C-S-H system has gradually made this dream a reality. But the extreme pressures required for the metallization of hydrogen-based superconductors limit their applications. In this work, we design a series of high temperature superconductors that can be stable at moderate pressures by incorporating heavy rare earth elements Yb/Lu into sodalite-like clathrate hydrides. In particular, the critical temperatures of Y3LuH24, YLuH12 and YLu3H24 are 283 K, 275 K and 288 K, respectively, which are close to or have reached room temperature, and the required pressure for stabilization of these hydrides is about 120 GPa which is significantly lower than that of reported room temperature superconductors. Our work provides an effective method for the rational design of low-pressure stabilized hydrogen-based superconductors with high-Tc and will stimulate further experimental exploration.
