| Abstract: | 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)x FeSe. 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. |
