摘要
自从2008年铁基超导体发现以来,人们探索并发现了一系列的铁基高温超导材料,其中FeSe基超导体因其具有的独特性质而引起了人们的广泛关注.本文主要介绍了两类新的铁基超导体,即水热合成法合成的(Li,Fe)OHFeSe及电化学插层方法合成的(CTA)_xFeSe的晶体结构及超导性质;对近年发展起来的利用电双层场效应晶体管技术以及固态离子导体调控FeSe的电子态性质的研究做了简要介绍.
Since the high-Tc superconductivity in iron-based superconductors was found in 2008, numerous new iron-based superconductors have been discovered. Of them, FeSe-based superconductors receive the most attention due to their unique properties. Here, we briefly introduce the structure and physical properties of two newly found FeSe-based superconductors, i.e.（Li, Fe） OHFeSe and（CTA）xFeSe. The former is synthesized by the hydrothermal method, while the latter is synthesized by electrochemical intercalation method. Moreover, we also introduce the tuning of electronic properties of FeSe by electric-double-layer and solid-ion-conductor based transistors.
