论文摘要
基于铁的超导体已经成长为高TC超导体的新大陆。在电子掺杂的1111型铁氧化剂中，56 K的最佳临界温度（TC）吸引了物理学家和化学家的极大关注。载体掺杂不仅是诱导超导性的必不可少的，而且是控制高-TC超导体中基态的电子，磁性和晶体学特性的关键参数。 Hydride离子（H-）是一种阴离子的氢气状态，在1111型中充当有效的电子供体，导致了几个重要发现，例如超导相和双方父阶段的两型摩尔结构。本文总结了H轴承1111型铁的超导体的合成，物理性质和电子结构以及其他超导体的相关现象。我们显示了高-TC超过50 K的铁基超导体的几个常见特征，并提出了一种实现较高TC的方法。
Iron-based superconductors have grown to be a new continent of high Tc superconductors comparable to cuprates. The optimal critical temperature (Tc) of 56 K in electron-doped 1111-type iron oxypnictides attracts considerable attention of physicists and chemists. Carrier doping is not only essential to induce superconductivity but also is a critical parameter that governs the electronic, magnetic, and crystallographic properties of ground states in high-Tc superconductors. Hydride ion (H-) which is an anionic state of hydrogen acts as an efficient electron donor in the 1111-type, leading to several important discoveries such as two-dome structure of superconducting phase and bipartite parent phase. This article summarizes the synthesis, physical properties, and electronic structure of the H- bearing 1111-type iron-based superconductors along with the relevant phenomena of other superconductors. We show several common characteristics of iron-based superconductors with high-Tc over 50 K and suggest a way to achieve higher Tc.
