论文摘要
基于铁的超导体中的新兴电子现象已经在凝结物理物理学的最前沿已有十多年了。关于有序阶段的起源和交织角色，包括nematicity，磁性和超导性在这种迷人的材料类别中，已经了解了很多了解。近年来，重点一直集中在FESE及其近亲的特殊和高度不寻常的特性上。由于发现了意外的超导间隙结构，广泛的超导临界温度以及非平凡的谱带拓扑的证据，包括相关的旋转性表面状态和涡流诱导的Majorana绑定状态，因此这种材料家族引起了很大的关注。在这里，我们审查了果皮辣椒剂超导的超导性超导率，包括散装的FESE，掺杂的散装FESE，FETE $ _ {1-x} $ se $ _X $ _x $，Intercalated FESE材料以及单层FESE和fete $ _ {1-x} $ _X $ se $ _x $ _X $ _X $ _X $ on srtio $ ___3 $ _3 $ _3 $ _3 $。我们专注于超导属性，包括对相关实验研究的调查，以及对不同理论配对情景的讨论。在本文的最后一部分中，我们回顾了越来越多的与FESE相关材料中非平凡拓扑作用的证据，再次集中在对超导性的有趣含义上。
Emergent electronic phenomena in iron-based superconductors have been at the forefront of condensed matter physics for more than a decade. Much has been learned about the origin and intertwined roles of ordered phases, including nematicity, magnetism, and superconductivity, in this fascinating class of materials. In recent years, focus has been centered on the peculiar and highly unusual properties of FeSe and its close cousins. This family of materials has attracted considerable attention due to the discovery of unexpected superconducting gap structures, a wide range of superconducting critical temperatures, and evidence for nontrivial band topology, including associated spin-helical surface states and vortex-induced Majorana bound states. Here, we review superconductivity in iron chalcogenide superconductors, including bulk FeSe, doped bulk FeSe, FeTe$_{1-x}$Se$_x$, intercalated FeSe materials, and monolayer FeSe and FeTe$_{1-x}$Se$_x$ on SrTiO$_3$. We focus on the superconducting properties, including a survey of the relevant experimental studies, and a discussion of the different proposed theoretical pairing scenarios. In the last part of the paper, we review the growing recent evidence for nontrivial topological effects in FeSe-related materials, focusing again on interesting implications for superconductivity.
