原始语种摘要: Iron-based superconductors have grown to be a new continent of high T c superconductors comparable to cuprates. The optimal critical temperature ( T c) 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- T c 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,...
