摘要:
芳烃类超导材料是一类新型有机超导材料,它以芳香烃分子晶体为基础,在分子间隙中掺入碱金属、碱土金属或稀土金属原子后形成新材料,可实现超导现象。芳烃类材料具有种类多样、易于剪裁和修饰、元素构成简单等优点。实验发现在芳烃分子晶体中掺入不同种类或数目的金属原子、以及施加压力时系统表现出丰富奇妙的物理现象,已引起科研人员的高度关注。文中概述了该领域实验和理论研究方面的主要进展,分析和总结该领域目前存在的困难和突出问题;同时,结合研究结果和对一些问题的理解,对芳烃类低温与超导体研究的发展态势进行讨论和展望。

Abstract: Aromatic superconductors discovered recently is a new class of organic superconductor, which is synthesized by doping alkali metal, alkali earth metal or rare earth metal into the molecular crystal of aromatic hydrocarbon to achieve superconducting phenomenon. Comparing with inorganic superconductor, aromatic superconductor has many advantages such as the molecule diversity, easiness of chemical modification and being composed of simple light elements. It is experimentally found that the system exhibits rich and interesting physical phenomena when the aromatic molecular crystal is doped by different kinds or number of metal atoms and is compressed, which has attracted researchers’ great attention. In this paper, the main progresses of experiment and theoretical research in the aromatic superconductor field are firstly introduced. And then the main problems and difficulties at present study are summarized. Combined the reported study results with the understanding of some problems, finally, the research perspectives and trends of low temperature and superconductor of aromatic hydrocarbon are discussed.
